• A subclass of quasi-acyclic automata with 2 inputs, n transient and k absorbing labeled states; square array T(n,k) read by descending antidiagonals (n >= 0 and k >= 1).at n=14A082171
• Number of permutations of decimal digits of 2^n which yield a prime.at n=34A086151
• Unreduced numerators of the elements T(n,k)/(n-k)!, read by rows, of the triangular matrix P^-1, which is the inverse of the matrix defined by P(n,k) = (1-(k+1)^2)^(n-k)/(n-k)! for n >= k >= 1.at n=10A103242
