group algebras of D4 and Q8.. please help!
ok this is my problem:
---------------------------------------------------------------------
for
D4 - the dihedral group of order 8
and
Q8 - quaternion group of order 8
describe the group algebra kG (for a big enough k so that Masche thm. holds), both its algebra and coalgebra structure.
---------------------------------------------------------------------
please if you have any suggestions how should i procede i'll be glad to see them
