If anyone is interested check out the nuclear tri-gram designations in the I Ching. Some are also used on the S Korean flag. They are a base 2 system to 64 places...from 0 to 63. Zero being - - used as a placeholder and --- used to designate value. Count from the bottom up with the bottom place being 1, next 2, next 4, next 8, next 16, and top 32. These markings are ancient, but they could very well be used to program gates for a base 64 system since gates are either on or off, 0 or 1. Comments??? David M Fisher sunfish@intercom.net
