Normal closure-finding problem

This article describes the subgroup operator computation problem for the subgroup operator: normal closure

Description

The normal closure-finding problem is the general name for a class of problems where a group $G$ is described using a group description rule, a subgroup $H$ is described using a subgroup description rule, and our goal is to use a (specified) subgroup description rule to find the normal closure $H^G$.
