Definition

The cyclic group of order sixteen, denoted C16,Z16 or sometimes Z/16Z, is the cyclic group having 16 elements. In other words, it is the quotient of the group of integers Z by the subgroup 16Z of multiples of 16.

It is given by the presentation:

xx16=e

where e is the identity element.

GAP implementation

Group ID

This finite group has order 16 and has ID 1 among the groups of order 16 in GAP's SmallGroup library. For context, there are groups of order 16. It can thus be defined using GAP's SmallGroup function as:

SmallGroup(16,1)

For instance, we can use the following assignment in GAP to create the group and name it G:

gap> G := SmallGroup(16,1);

Conversely, to check whether a given group G is in fact the group we want, we can use GAP's IdGroup function:

IdGroup(G) = [16,1]

or just do:

IdGroup(G)

to have GAP output the group ID, that we can then compare to what we want.
