Direct product of E16 and Z4

Definition
This group is defined as the uses as intermediate construct::external direct product of the elementary abelian group of order sixteen and the cyclic group of order four.

It can be defined as the abelian group of prime power order for the prime $$2$$ and the partition $$6 = 2 + 1 + 1 + 1 + 1$$.

Other descriptions
The group can be defined using GAP's CyclicGroup, DirectProduct, and ElementaryAbelianGroup functions:

DirectProduct(ElementaryAbelianGroup(16),CyclicGroup(4))
