The following used to work (based on regular private doctesting outside of Sage source code) and give you the path you wanted:
P9 = Graph([[0..8], lambda i,j: i-j == 1]) Now it silently produces an empty graph (9 vertices, no edges). The fix: P9 = Graph([[0..8], lambda i,j: i-j == -1]) Is this a bug, or does part 4 of the Graph() constructor documentation need clarification?
