Comments

The motivation for these two sequences is that the order-168 Kleinian n=7 group seems to demand a non-Euclidean E9 type of manifold and my work in cosmology led me to think in terms of an E10 exceptional group.

Programs

Mathematica

b0 = {3, 15, 24, 48, 72, 120, 168, 264}
b = Table[If[n <= 8, b0[[n]], Prime[n]*24], {n, 1, 25}]

Formula

Limit_{n->oo} A129025(n)/A129024(n) = 2.
