Commentary

Size-91 (= 13 × 7) right-cancellative fiber bundle: F_13(9,11) base × F_7(4, 1) fiber, in a "twisted" Family B variant. The 91 elements partition into 13 fibers of 7 (a non-trivial congruence with F_13 quotient); 1 of the 13 fibers are themselves sub-magmas ≅ F_7(4, 1), and the rest are non-closed congruence classes. The full magma is a quasigroup (LC + RC) with a unique idempotent.
