%F A089258 For n>0, T(n, k) is the permanent of the n X n matrix with k on the diagonal 
               and 1 elsewhere; T(0, k) = 1. T(n, k) = Sum(j>=0; A008290(n, j)*k^j). 
               T(n, k) = n*T(n-1, k) + (k-1)^n . T(n, k) = n!*Sum(j=0..n; (k-1)^j/
               j! ) For column k, E.g.f. : exp((k-1)*x/(1-x)).
