Re: Mersenne: Re: Smooth and hairy numbers
I would be more worried about a more exact definition of the word small. -Original Message- From: Robert G.

"And Jacob said to Rebekah his mother, Behold, Esau my brother is a hairy man, and I am a smooth man:" (Gen. 27:11) Also, Greek has smooth and rough breathing, called psilé kai daseia. Daseia means hairy. I looked in Eric Weisstein's World of Mathematics and found no hairy numbers. There are, though, a Hairy Ball Theorem (the hair has to have a whorl or other singularity somewhere) and Haar integral, function, measure, and transform (one cycle of a square wave at a power-of-two frequency). phma _ Unsubscribe list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
