The Coxeter clock and its quarter action

Original ledger classification: Identity (exact)

Recorded statement: COXETER TOTATIVE CLOCK (2026-06-16): the mu4 clock is the order-4 character of the E8 Coxeter cycle. (Z/30)^x={1,7,11,13,17,19,23,29}=the E8 exponents=live Coxeter phases; phi(30)=8=rank E8, 30=|Z2|*N_fam*g_car=2*3*5. (Z/30)^x ~ Z/4 x Z/2,…

Original claim text

COXETER TOTATIVE CLOCK (2026-06-16): the mu4 clock is the order-4 character of the E8 Coxeter cycle. (Z/30)^x={1,7,11,13,17,19,23,29}=the E8 exponents=live Coxeter phases; phi(30)=8=rank E8, 30=|Z2|*N_fam*g_car=2*3*5. (Z/30)^x ~ Z/4 x Z/2, order-4 generator 7 (7^2=19,7^4=1 mod 30): a literal mu4 clock <7>={1,7,13,19} on the exponents; conjugate pairs m+(30-m)=30 give |mu4|=4 invariant 2-planes the clock permutes. Only E8 has phi(h)=rank AND h=2*3*5. Complements MCKAY.E8.01 (McKay gives (2,3,5) from the finite group, this gives mu4 from the Coxeter cycle).

Original classification detail

[E] (Z/30)^x = E8 exponents, order-4 element 7 = mu4 clock on the exponents, 4 invariant planes; seam-clock identification [C]

These document locations are recorded directly on the ledger row. They are document level navigation, rather than a newly inferred section citation.

Sections that explicitly cite this claim

A literal claim identifier is present in these paper sections. The section and its premises determine what the citation supports.

Navigation through a shared verification script

These sections cite a script associated with the claim. This is a source navigation join, rather than an explicit citation of the claim or a theorem equivalence.

    The μ₄ clock is the order-4 character of the E₈ Coxeter cycle. (ℤ/30)ˣ={1,7,11,13,17,19,23,29}=the E₈ exponents=live Coxeter phases; φ(30)=8=rank E₈, 30=2·3·5. (ℤ/30)ˣ≅ℤ/4×ℤ/2 with order-4 generator 7 (7²=19,7⁴=1 mod 30): a literal μ₄ clock ⟨7⟩={1,7,13,19} on the exponents; conjugate pairs m+(30−m)=30 give |μ₄|=4 invariant planes the clock permutes. Only E₈ has φ(h)=rank AND h=2·3·5.
