Wielandt-Kegel theorem (Theorem)
Theorem   If a finite group is the product of two nilpotent subgroups, then it is solvable.

That is, if $H$ and $K$ are nilpotent subgroups of a finite group $G$, and $G=HK$, then $G$ is solvable.

This result can be considered as a generalization of Burnside's $p$-$q$ Theorem, because if a group $G$ is of order $p^m q^n$, where $p$ and $q$ are distinct primes, then $G$ is the product of a Sylow $p$-subgroup and Sylow $q$-subgroup, both of which are nilpotent.
