This may help: sage: sage.matrix.action.MatrixMatrixAction(N.parent(),T.parent()).codomain() Full MatrixSpace of 2 by 2 dense matrices over Ring of integers modulo 1 sage: A=matrix(GF(25,'a'),[[1,1],[0,3]]) sage: sage.matrix.action.MatrixMatrixAction(N.parent(),A.parent()).codomain() sage: G=N.parent() sage: S=T.parent() sage: from sage.categories.pushout import pushout sage: base = pushout(G.base_ring(), S.base_ring()) sage: base Ring of integers modulo 1 sage: pushout(QQ,GF(7)) Ring of integers modulo 1 sage: pushout(QQ,GF(7^2,'b')) Finite Field in b of size 7^2
so something goes wrong in that pushout. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
