MATCH(with a font caveat) In a plain lowercase sans-serif, exactly 13 of the 26 letters map onto a letter under 180° rotation: the self-maps l o s x z and the pairs b↔q, d↔p, n↔u, m↔w (m↔w depends on the font). That is the set {b, d, l, m, n, o, p, q, s, u, w, x, z}, exactly half the alphabet. Letters like a, e, h, y only approximate other letters (ɐ, ǝ, ɥ, ʎ), so they are excluded.

MATCHApplied to the pair cipher's surviving coefficients (a×1, odd letters ×2, s×3): the rotatable letters carry m×2, o×2, q×2, s×3, u×2, w×2, a coefficient sum of 13, worth 235 with a = 1 … z = 26. After rotation q→b, u→n, m→w, w→m and s, o stay put: the coefficients become b×2, m×2, n×2, o×2, s×3, w×2, still summing to 13, now worth 191. The 13 non-rotating letters drop out entirely.

MODELReading these 13 as Dave’s "13" is an interpretation. Tap to spin the alphabet.
