- Subhomomorph-containing subgroup: For proof of the implication, refer subhomomorph-containing implies right-transitively homomorph-containing and for proof of its strictness (i.e. the reverse implication being false) refer right-transitively homomorph-containing not implies subhomomorph-containing.
