Conjectures from R. J. Mathar, May 25 2010: (Start)

a(n) = 2*8^n-9*6^n/2+12^n+18^n/2+10^n.

a(n) = 54*a(n-1) - 1124*a(n-2) + 11304*a(n-3) - 55008*a(n-4) + 103680*a(n-5).

G.f.: 4*x*(-5+177*x-2022*x^2+7488*x^3) / ( (12*x-1)*(6*x-1)*(8*x-1)*(18*x-1)*(10*x-1) ). (End)

Sequence in context: A290581 A000564 A365415 * A266736 A019580 A177109
