LINKS

Table of n, a(n) for n=0..14.

FORMULA

a(n)=A129467(n+3,3),n>=0.

a(n) = (-1)^n*det(PS(i+3,j+2), 1 <= i,j <= n), where PS(n,k) are Legendre-Stirling numbers of the second kind (A071951). [Mircea Merca, Apr 06 2013]

EXAMPLE

a(3)=-det([20,1,0],[292,40,1],[3824,1092,70])=-17544 [Mircea Merca, Apr 06 2013]
