A topologically quasihamiltonian group $G$ is defined by the property that any two closed subgroups $X$ and $Y$ give rise to a closed subgroup $\overline{XY}=\overline{YX}$. Y.\,N.\,Mukhin employed lattice theoretic arguments for proving that any such group with a connected component not a singleton set must be commutative. We reprove here this fact -- using only standard arguments from topological group theory.
