Revision history [back]

I don't agree with your very offensive criticism about pretzels.

This being said, and if you have no taste for food, you can give this a try :

sage: # Displays a Pretzel
sage: digraphs.Circuit(100).show()
sage: # Displays a calamari
sage: digraphs.Circuit(100).show(iterations=20000)

Now that I think of it, given the choice I would also chose a calamari over a pretzel.

Hence it all makes sense, after all.
