Please Help!

I am trying to represent and view the projectivve specail linear group
(for example, L_2(13) ). One can easily construct the group using GAP's
SL(2,13) special linear group command in conjunction with the FactorGroup
command.

However... when i ask GAP to list the generators of the group, it produces
two group elements: one of order 6 and one of order 3. I wish to express
the group with two generators, one of order 2 and one of order 7. I am
certain this can be done ('the atlas of finite groups' asserts the
gereators existance, buuut not their form), but am unable to get GAP to
help me to this end - any suggestions??

Thanks _very_ much,
