[sage-devel] Meaning of edge_labels in canonical_label()

[Jori Mäntysalo]

Using edge_labels=True in canonical_label() of graph seems to work, i.e. 
canonization transforms isomorphism to equality. Also the parameter does 
*something*, it is not ignored.

But what is the meaning of it? For partition-parameter the meaning is 
clear (but not clearly documented).
