%N The first 8 values are predefined, the remaining set to a(n) = 48*prime(n)+n+2.

%C 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.

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

%t a0 = {14, 52, 78, 133, 152, 248, 345, 538}

%t a = Table[If[n <= 8, a0[[n]], Prime[n]*48 + n + 2], {n, 1, 25}]
