Converting to a set is the best way to go. You can convert [1, 2] to something like "001002" and use that if you first locate, or already know the largest number. The brute force way is to loop through the list and compare this sub-list with list[N+1], then list[N+2], to the end of the list. If not found then append to a second list. -- http://mail.python.org/mailman/listinfo/python-list
