Please make a donation to keep the OEIS running. We are now in our 55th year. In the past year we added 12000 new sequences and reached 8000 citations (which often say "discovered thanks to the OEIS"). We need to raise money to hire someone to manage submissions, which would reduce the load on our editors and speed up editing.

FORMULA

G.f.: conjecture T(0)/(1+7*x), where T(k) = 1 - 64*x^2*(k+1)^2/(64*x^2*(k+1)^2 + (1+7*x)^2/T(k+1) ); (continued fraction). - Sergei N. Gladkovskii, Nov 12 2013

a(n) = (-8)^n*skp(n, 7/8), where skp(n,x) are the Swiss-Knife polynomials A153641. - Peter Luschny, Apr 19 2014
