## Definition

Suppose is a finite group. The **socle over solvable radical** of , denoted , is defined as the unique subgroup of such that contains the solvable radical of and the quotient group is the socle of the quotient group .

## Facts

If is the socle over solvable radical of , then and is a direct product of simple non-abelian groups.
