Definition with symbols

A subgroup H of a finite group G is termed a pronormal Hall subgroup if it satisfies the following two conditions:

  1. H is a Hall subgroup of G: The order and index of H in G are relatively prime.
  2. H is a pronormal subgroup of G: If K is a conjugate subgroup to H in G, then H, K are conjugate subgroups inside \langle H, K \rangle.
