%N Triangular matrix, read by rows, that satisfies: T(n,k) = [T^3](n-1,k) when n>k>=0, with T(n,n) = (n+1).
%C Column 0 forms A082162. Column 1 forms A102099. Row sums form A102100. This triangle is a variant of A102086.
%F T(n, 0) = A082162(n) for n>0, with T(0, 0) = 1.
%e Rows of T begin:
%e [1],
