For a finite group G and an arbitrary prime p, let denote the intersection of all maximal subgroups M of G such that [G:M] is both composite and not divisible by p; if no such M exists we set = G. Some properties of G are considered involving . In particular, we obtain a characterization of G when each M in the definition of is nilpotent.
