Computer algebra can be very frustrating when your questions are SO
specific. What you want to do is first understand why your problem is
equivalent to the following.
List all the pairs [a,b] where a and b come from the set {1,2,3}.
Then the answer to the second problem in GAP is given by the following command.
gap> Tuples([1,2,3],2);
[ [ 1, 1 ], [ 1, 2 ], [ 1, 3 ], [ 2, 1 ], [ 2, 2 ], [ 2, 3 ], [ 3, 1
], [ 3, 2 ], [ 3, 3 ] ]
You can find out more about the Tuples command by typing
?Tuples
Best of luck!
