A subgroup of a group is said to be permutable subgroup if
and only if for every subgroup of . Certainly, every
normal subgroup is permutable. The converse is not true. In this
research we will find all permutable subgroups of the groups of
order . Then, find which subgroup is permutable and not normal.
