Direct product of M16 and Z4
This article is about a particular group, i.e., a group unique upto isomorphism. View specific information (such as linear representation theory, subgroup structure) about this group

This group is defined as the external direct product of the group M16 (which is a semidirect product of cyclic group:Z8 and cyclic group:Z2 acting via the multiplication by five map) and cyclic group:Z4.

This finite group has order 64 and has ID 85 among the groups of order 64 in GAP's SmallGroup library. For context, there are groups of order 64. It can thus be defined using GAP's SmallGroup function as:
For instance, we can use the following assignment in GAP to create the group and name it :
gap> G := SmallGroup(64,85);
Conversely, to check whether a given group is in fact the group we want, we can use GAP's IdGroup function:
IdGroup(G) = [64,85]
or just do:
to have GAP output the group ID, that we can then compare to what we want.
