Annual Appeal: Please make a donation to keep the OEIS running. In 2018 we replaced the server with a faster one, added 20000 new sequences, and reached 7000 citations (often saying "discovered thanks to the OEIS").

Wikipedia, Young tableau

Index entries for linear recurrences with constant coefficients, signature (9,-36,84,-126,126,-84,36,-9,1).

FORMULA

a(n) = n^2*(n^2+3)*(1124+(1205+191*n^2)*n^2)/10080.

G.f.: -x*(x+1)*(x^6+15*x^5+90*x^4+170*x^3+90*x^2+15*x+1)/(x-1)^9.

MAPLE

a:= n-> n^2*(n^2+3)*(1124+(1205+191*n^2)*n^2)/10080:

seq(a(n), n=0..40);

CROSSREFS
