test whether one group is contained in another
IsSubgroup( H, G )
A group H is a subgroup of a group G if H is contained in G and the binary operation on H is the restriction of the binary operation on G to H.
The IsSubgroup( H, G ) command tests whether the group H is a subgroup of the group G. It returns true if H is a subgroup of G, and returns false otherwise. For some pairs H and G of groups, the value FAIL may be returned if IsSubgroup cannot determine whether H is a subgroup of G.
The GroupTheory[IsSubgroup] command was introduced in Maple 17.
