# Conjugates Generating a regular subgroup

This trouble is extracted from I.N. Herstein

**Problem : **

If $G$ is a team and also $a \in G$ if of limited order and also has just a limited variety of conjugates in $G$, confirm that these conjugates of $a$ create a limited regular subgroup of $G$.

I would love to see a remedy for this as well as additionally I would love to recognize whether the conjugates constantly create a regular subgroup.

This called Dicman's lemma and also is 14.5.7 on web page 425 (1st ed) or page 442 (2nd ed) of Robinson's Course in the Theory of Groups.
