[sage-support] Distinguishing vertices of DiGraph

I have a tree structure where the same point shows up on different levels, but I want to treat these as distinct points on the graph. Currently the only workaround is to add an integer to each of the points to distinguish them. Is there a way to change the label on the vertex but keep the points

[sage-support] problem with matrix over finite field

This works on sage-8.5: sage: a = var('a') : matrix(GF(25, a), [[1,0], [0, 1]]) : [1 0] [0 1] but not on sage-8.6 or later: sage: a = var('a') : matrix(GF(25, a), [[1,0], [0, 1]]) : p025.zzz: No such file or directory
