Formula

a(n) = A008290(n,11).

E.g.f.: exp(-x)/(1-x)*(x^11/11!) . [Zerinvary Lajos, Apr 03 2009]

O.g.f.: (1/11!)*Sum_{k>=11} k!*x^k/(1 + x)^(k+1). - Ilya Gutkovskiy, Apr 15 2017

Maple

a:=n->sum(n!*sum((-1)^k/(k-10)!, j=0..n), k=10..n): seq(a(n)/11!, n=10..27);
restart: G(x):=exp(-x)/(1-x)*(x^11/11!): f[0]:=G(x): for n from 1 to 29 do f[n]:=diff(f[n-1], x) od: x:=0: seq(f[n], n=11..27); # Zerinvary Lajos, Apr 03 2009
