Abstract
Let be an elliptic curve. When the symmetric group of order acts on in the natural way, the subgroup , consisting of those -tuples whose coordinates sum to zero, is stable under the action of . It is isomorphic to . This paper concerns the structure of the quotient variety when is a subgroup of generated by simple transpositions. In an earlier paper we observed that is a bundle over a suitable power, , with fibers that are products of projective spaces. This paper shows that has an \'etale cover by a product of copies of and projective spaces with an abelian Galois group.
