I've been following along. The early suggestion to double one list and see if the second list is in the double list seems to prove they are the same -- one is just rotated to a different starting point. I don't understand the term 'canonical' in this example, but what is it that the solution given doesn't provide for you? -- Joel Goldstick http://joelgoldstick.com -- https://mail.python.org/mailman/listinfo/python-list
