%N Triangle read by rows. The incomplete Bell transform of the central binomial numbers.

%F Given a sequence s let s|n denote the initial segment s(0), s(1), ..., s(n).

%F (T(s))(n, k) = IncompleteBellPolynomial(n, k, s|n) where s(n) = binomial(2*n, n).

%e Triangle starts:

%e [0] 1;

%e [1] 0, 1;

%e [2] 0, 2, 1;

%e [3] 0, 6, 6, 1;

%e [4] 0, 20, 36, 12, 1;

%e [5] 0, 70, 220, 120, 20, 1;
