  Let Heis(F) be the Heisenberg group over the field F with the group operation being matrix multiplication. Show that if F is finite of order q then the order of Heis(F) is q3; conversely show that if F is infinite then Heis(F) is infinite.

Question
1. Let Heis(F) be the Heisenberg group over the field F with the group operation being matrix multiplication. Show that if F is finite of order q then the order of Heis(F) is q3; conversely show that if F is infinite then Heis(F) is infinite.

Step 1

To establish tha tthe group  Heis(F) has the  required orders, when F is finite or infinite

Step 2
