Various combinatorial problems that occur in algebraic and computer scientific context are considered. The minimal Hamming distance (minimal number of differing entries) between multiplication tables of non-isomorphic groups. Congruences mod powers of prime ideals satisfied by certain generalized Stirling numbers that occur as coefficients of interesting integer-valued polynomials. Computing the number of artificial neural networks (ANN).
