Sefer, Sefar, Sippur ↔ It from Bit

Sefer Yetzirah: reality is engineered from letters — text (sefer), number (sefar), story (sippur) as the three registers of one code. Wheeler (1989): "it from bit" — every physical thing derives from binary answers; the universe as information first, stuff second. Digital physics and the computational-universe programs are Sefer Yetzirah's register naturalized: creation as combinatorics on a small alphabet. The 231 gates are, formally, the complete graph K22 — the tradition drew the adjacency matrix of its alphabet seventeen centuries early.
