There are hints on the site; for level 10, http://www.pythonchallenge.com/forums/viewtopic.php?t=20 > I came up with what I thought was a perfectly good > solution, but apparently it's wrong. :-( The On-Line Encyclopedia of Integer Sequences should be better known -- it's an amazing resource: http://www.research.att.com/~njas/sequences/ It knows about this sequence, so don't use it unless you want the answer given to you. If it doesn't know about your sequence, "perfectly good" is debatable <wink>. -- http://mail.python.org/mailman/listinfo/python-list
