I found it. Thank you.
I also tried the command listed above.
I am confused. Where is this "I]~~~~~~w"?
Is it a file? How did Graph load this?
In my program, my code looks like this:
i=12
for G in graphs.nauty_geng(str(i) + " -C"):
q = True
for j in range (0,i):
S = Sandpile(G,j)
if S.identity() != S.max_stable():
q = False
break
If I use geng to generate graphs, how should I load them in my for loop so
I can check with Sandpile?
Sorry for being new in Sagemath. Thank you all for the help.
