Consecutive internal states of the linear congruential pseudo-random number generator (7141·s + 54773) mod 259200 when started at 1. A385463

Triangle T(n,k,2) read by rows (generalized q-Stirling numbers of second kind): T(n, k, q_) = (1/(q - 1)^k)*Sum[(-1)^{k - j}*q·Binomial[k + n, k -j] - Binomial[j + n, j, q - 1], {j, 0, k}], with q=2, where Binomial[,] is the Gaussian q-binomial coefficient as in A022166. A156823
