Index entries for linear recurrences with constant coefficients, signature (11,-55,165,-330,462,-462,330,-165,55,-11,1).
FORMULA
a(n) = (16*n^10+80*n^9+120*n^8-147*n^6-105*n^5+5*n^4+25*n^3+6*n^2)/525. - Colin Barker, Jun 29 2015
G.f.: -144*x^2*(x^6+31*x^5+187*x^4+330*x^3+187*x^2+31*x+1) / (x-1)^11. - Colin Barker, Jun 29 2015
EXAMPLE
n=3: 6048 = 1588*28 - 196^2.
