Definition with symbols

A subgroup H of a group G is termed polynomial-bound join-transitively subnormal in G if there exists a polynomial f with integer coefficients such that if K is a k-subnormal subgroup of G, \langle H, K \rangle (the join of subgroups) is a f(k)-subnormal subgroup of G.

Here, a k-subnormal subgroup is a subgroup whose subnormal depth is at most k.
