We present a mechanical model of the prime hierarchy in which
each prime is a rotor with teeth offset from the previous rotor
by the golden angle θg = 360∘ / φ2
≈ 137.507764∘. The simultaneous-engagement
patterns of a k-rotor assembly are in bijection with the
antichains of the Boolean lattice 2[k], so the number of
valid mechanical states is the Dedekind number D(k). We prove
the bijection, identify the irrationality of φ as the
unique property that makes the construction work, derive the
Sperner upper bound on the configuration count, and use that
bound to fix the size of a k ≈ 13 configuration
database at roughly 22370 states. We close by noting that
the numerical value of θg and the value of the
first-half ladder ceiling (137 = P33 = 1/α) are the
same fact.
1IntroductionIn Article 0 we introduced Dedekind numbers as the count of
independent configurations at each level of the prime hierarchy,
and sketched a mechanical interpretation in which primes are
rotors at the golden angle. The present article develops that
interpretation in full: it proves the bijection between
mechanical states and antichains, establishes the Sperner bound
on the state count, and uses the bound to derive an explicit
size estimate for a k = 13 configuration database.The model is not a visualization of an abstract combinatorial
fact. It is a physical realization of the fact, and the physical
realization explains why the count is exactly D(k) and not
some other number.Unrecognized environment: keyideaPrimes are rotors, the golden angle is the unique offset that keeps them non-resonant, and the Dedekind numbers count the states that the as2The gear assemblyDefinitionA prime rotor of index i is a circle of circumference

that depends on the index according to the offset rule below.DefinitionThe golden angle is

where φ = (1 + √(5))/2 is the golden ratio. The
rotor of index i is offset from the reference position by
i · θg.DefinitionThe gear assemblyGk of order k is the ordered
tuple of prime rotors (1, …, k) with offsets
(θg, 2θg, …, kθg).The rotors do not physically interact: they rotate independently.
But their teeth sweep past a common reference line, and the
simultaneous engagement pattern at any instant is the
set of rotors whose teeth are at the reference line at that
moment.3The no-resonance theoremThe key property of the golden angle is that it prevents any
finite rational reconciliation between rotors.TheoremFor any two distinct indices i ≠ j and any pair of
non-zero integers (m, n), the rotors i and j
under golden-angle offsets never satisfy
m i θg = n j θg 2π.
