The dicyclic group is a non-abelian group of order $4n$ which contains a cyclic subgroup of order $2n$ for $n\>1$.

The DicyclicGroup( n ) command returns a dicyclic group, either as a permutation group (the default) or as a finitely presented group.

You can specify the form of the group returned explicitly by passing one of the options 'form' = "permgroup" or 'form' = "fpgroup".

If the parameter n is not a positive integer, then a symbolic group representing the dicyclic group of order 4*n is returned.

In the Standard Worksheet interface, you can insert this group into a document or worksheet by using the Group Constructors palette.
