in reply to How many different varieties (color, size, etc) of socks do you have in your sock drawer?

All my socks, both two types of "normal" socks, my white badminton sporting socks, and several bright-colored skiing sock pairs do not just come in pairs: they are all seamless and have a right-fit and a left-fit. All these math riddles assume left and right socks to be equal.


Enjoy, Have FUN! H.Merijn

    they are all seamless and have a right-fit and a left-fit.

    You can turn a left-fit into a right-fit and vice versa, if you treat them as Inside-Out-Objects. More math ;-)
