GTE Orbits: From Arithmetic to Particle Masses

Two arithmetic steps from a single seed — and the three charged lepton generations appear, with no free parameters.

What Is GTE?

GTE stands for Generative Triple Evolution. The name describes the mechanism precisely: it generates triples of integers, and it evolves them through a deterministic arithmetic orbit — like a crystal growth law where each step is forced by the geometry of the previous one.

Each state in the orbit is an integer triple (a, b, c) at generation g. The three components play distinct roles:

a
Parity phase
Tracks the step parity; equals Nc² at odd steps
b
Ladder index (N-value)
This is the key output — the arithmetic address of a particle generation
c
Capacity
The divisor at each step; saturates to Mersenne numbers at the ridge

The particle masses come from the b-values. The three generations of charged leptons correspond to the three b-values produced by two applications of the map: b = {73, 42, 275}.

The Map T

The GTE update map T takes a triple (a, b, c) and a step type (odd or even) and produces the next triple. The mechanism: divide the capacity c by the ladder index b to get a quotient q and remainder m. These two numbers control the update of all three components.

The GTE map T (ridge n = 10, Nc = 3)

Step 0 — Divide:

c ÷ b → quotient q, remainder m    (so c = b·q + m)

Odd step (t = 1):

a' = m − (n + 2 − t)
b' = b − (m + q)
c' = 2ⁿ − 1  (ridge Mersenne)

Even step (t = 2):

a' = m − (n + 2 − t)
b' = b + F|q₂−q₁|
c' = 2n+2Nc − 1

Fk is the k-th Fibonacci number. The odd step contracts b (subtraction). The even step lifts b by a Fibonacci number. No free parameter appears anywhere.

The Lepton Seed

The starting point of the GTE lepton orbit is the Lepton Seed:

Generation g = 1
a
1
parity phase
b
73
N-value (electron address)
c
823
capacity

Where does (1, 73, 823) come from? It is the unique triple at ridge level n=10 that passes all four UGP invariants simultaneously — ridge lock, Fibonacci rigidity, kernel symmetry, and mirror invariance. It is not chosen. The MDL sieve and mirror constraints force it. 73 is prime (mirror-lock condition). 823 = 73×11 + 20 (the division structure is exact).

The Worked Cascade — Two Steps, Three Generations

Starting from the Lepton Seed, apply T twice. Every number below can be verified with pencil and paper.

Starting triple: the Lepton Seed at generation 1.

a
1
b
73
electron N-value
c
823

Apply map T with odd step (t=1). First: divide c by b.

Odd step (t = 1) — divide c by b:

Division

823 ÷ 73 = 11 remainder 20

Check: 73 × 11 = 803    803 + 20 = 823 ✓

q₁ = 11 (quotient)
m₁ = 20 (remainder)

The quotient q₁ = 11 and remainder m₁ = 20 now drive the update of all three components.

Odd step (t = 1) — update all three components:

Update rules (odd step, n=10, t=1)

b' = b − (m₁ + q₁) = 73 − (20 + 11) = 73 − 31 = 42

c' = 2¹⁰ − 1 = 1024 − 1 = 1023  (ridge Mersenne)

a' = m₁ − (n + 2 − t) = 20 − (10 + 2 − 1) = 20 − 11 = 9

a
9
= N_c² = 3²
b
42
muon N-value
c
1023
= 2¹⁰ − 1

b' = 42 is the muon's arithmetic address. a' = 9 = N_c² is a machine-certified algebraic identity — not an assignment.

Even step (t = 2) — divide c by b:

Division

1023 ÷ 42 = 24 remainder 15

Check: 42 × 24 = 1008    1008 + 15 = 1023 ✓

q₂ = 24 (quotient)
m₂ = 15 (remainder)

m₂ = 15 is not a coincidence. The ridge remainder lock theorem proves: for any valid divisor b₂, (2ⁿ−1) mod b₂ = 15 when n ≥ 5. Since b₂ = 42 divides R₁₀ = 1008, the remainder 15 is structurally guaranteed.

The quotient gap and the Fibonacci lift:

Quotient gap

|q₂ − q₁| = |24 − 11| = 13

The gap is 13. The Fibonacci sequence at position 13:

112 358 132134 5589144 233 = F₁₃

The even step lifts b by F₁₃ = 233. This is not a free parameter — once the quotient gap is forced to 13 by the orbit structure, the Fibonacci lift is uniquely determined: b' = 42 + 233.

Why Fibonacci specifically? The gap 13 is itself the Fibonacci number F₇, where the index 7 = ord₇(2) + Nc + 1 is forced by the Z₇×Z₃ algebra. Here ord₇(2) = 3 is the multiplicative order of 2 modulo 7 (the unique k with 2k ≡ 1 mod 7, giving k = 3), and Nc = 3 is the QCD color rank. The Fibonacci recurrence is not a separate assumption — it is a consequence of the arithmetic structure, machine-certified by a computer proof system (Lean 4) that verifies every step automatically, with zero sorry.

Even step (t = 2) — update all three components:

Update rules (even step, n=10, N_c=3, t=2)

b' = b + F₁₃ = 42 + 233 = 275

c' = 2^(10 + 2×3) − 1 = 2¹⁶ − 1 = 65536 − 1 = 65535

a' = m₂ − (n + 2 − t) = 15 − (10 + 2 − 2) = 15 − 10 = 5

a
5
= (N_c²+1)/2
b
275
tau N-value
c
65535
= 2¹⁶ − 1

b' = 275 is the tau lepton's arithmetic address. c' = 65535 = 2¹⁶ − 1 is another Mersenne number. a' = 5 = (N_c² + 1)/2 — another structural identity. Zero free parameters throughout.

Note on 1023 and 65535: The odd step produces c = 2¹⁰ − 1 = 1023; the even step extends it to 2^(n + 2Nc) − 1 = 2¹⁶ − 1 = 65535 (the exponent jump 2Nc = 6 carries the ridge from n=10 to 16). Both values are identical in GF(7) arithmetic — 1023 ≡ 1 mod 7 and 65535 ≡ 1 mod 7 — so the polynomial dynamics are unaffected. The distinction matters for the physical mass predictions, where the actual Mersenne value enters the mass formula.

The three lepton generations — result of two forced steps:

GenTriple (a, b, c)N-value (b)Particle
g = 1 (seed)(1, 73, 823)73Electron
g = 2 (odd step)(9, 42, 1023)42Muon
g = 3 (even step)(5, 275, 65535)275Tau

The three N-values {73, 42, 275} are the output of two forced arithmetic steps from a sieve-forced seed. They are the arithmetic addresses from which the electron, muon, and tau masses are derived.

Why Three Generations? And Is This Just a Fit?

Why exactly Ngen = 3

The map T produces three triples because the orbit terminates at three steps under the structural constraints. This is not a parameter — Ngen = 3 is forced by seven independent structural conditions, all machine-certified in Lean 4.

Seven independent Lean-certified constraints each force Ngen = 3 independently. One master theorem certifies that all seven hold simultaneously.

The same arithmetic that produces three lepton generations produces exactly three quark generations — forced by the same constraints.

This is not numerology

A natural suspicion: "These numbers were chosen to match the particle masses." This suspicion is addressed directly by a null test.

1000-permutation null test: Take the orbit values {73, 42, 275} and scramble their order in 1000 random permutations. Apply the mass formula to each permutation. How many match the SM lepton masses within 1σ?

Answer: zero. Only the orbit order derived by the map T matches.

The N-values are not labels you can rearrange. They carry arithmetic structure (73 is prime, 42 = 6×7, 275 = 5²×11) that is specific to their position in the orbit. Permuting them destroys the mass predictions.
