Abstract: Let E be an elliptic curve over 'Q' with identity. We can study the absolute Galois group of 'Q', 'GQ', by studying the representations associated to E. The Tate representations recover the action of 'GQ' on the abelianization of the tale fundamental group of E\{}. Grothendieck defined a much more general representation. To understand it more concretely, we study some nonabelian tale covers and the resulting Galois representations.
