Abstract

Let H,KH, K be subgroups of the permutation group GG of degree nn with KGK\trianglelefteq G and σ\sigma be a partition of the set of all different prime divisors of G/K|G/K|. We prove that in polynomial time (in nn) one can check G/KG/K for σ\sigma-nilpotency and σ\sigma-solubility; H/KH/K for σ\sigma-subnormality and σ\sigma-pp-permutability in G/KG/K. Moreover one can find the least partition σ\sigma of π(G/K)\pi(G/K) for which G/KG/K is σ\sigma-nilpotent. Also one can find the least partition σ\sigma of π(G/K)\pi(G/K) for which H/KH/K is σ\sigma-pp-permutable in G/KG/K.
