The "for" loop over each possible bit in the input values. The "map" function over the parity bits accumulated up to that point. And the "+=" operator over those same bits again. Make that *three* sets of bits. I stand humbled. Regards, Dan -- Dan Sommers <http://www.tombstonezero.net/dan/> Îâ à Îâ à c = 1 -- http://mail.python.org/mailman/listinfo/python-list
