Bigrading is a very interesting solution. I take it that the differential should have degree (1,0).
Sorry I forgot to answer that. The differential must have total degree 1 (that is, bidegree (i,j) with i+j = 1). So in your case, just change every degree i to (i,2). -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
