Wikipedia, Young tableau
Index entries for linear recurrences with constant coefficients, signature (11,-55,165,-330,462,-462,330,-165,55,-11,1).
FORMULA
a(n) = n^2*(126432+(206020+(101031+(18930+1187*n^2)*n^2)*n^2)*n^2)/453600.
G.f.: -x*(x+1)*(x^8 +24*x^7 +265*x^6 +1132*x^5 +1904*x^4 +1132*x^3 +265*x^2 +24*x+1) / (x-1)^11.
MAPLE
a:= n-> n^2* (126432+ (206020+ (101031+ (18930+ 1187*n^2) *n^2) *n^2) *n^2)/ 453600:
seq(a(n), n=0..40);
