Direct product of Z9 and Z9 and Z3

Definition
This group is defined as the external direct product of two copies of the cyclic group of order 9 and one copy of the cyclic group of order 3. In other words, it is:

$$\Z_9 \times \Z_9 \times \Z_3$$

Other descriptions
The group can also be described using GAP's CyclicGroup and DirectProduct functions as:

DirectProduct(CyclicGroup(9),CyclicGroup(9),CyclicGroup(3))
