Talk:Dihedral prime

I've just removed the following:


 * "In binary, all primes are dihedral."

I've no idea where that claim came from. First few counterexamples: -- Smjg 17:19, 3 March 2007 (UTC)
 * 2 &rarr; 10 &rarr; 01
 * 19 &rarr; 10011 &rarr; 11001 &rarr; 25
 * 59 &rarr; 111011 &rarr; 110111 &rarr; 55
 * 79 &rarr; 1001111 &rarr; 1111001 &rarr; 121


 * You're absolutely right. At face value, it was a false statement. It probably came from my study of palindromic primes in binary and I probably forgot the word "palindromic" when I put it in here (I forget lots of things these days). Well, that's the beauty of talking about actual numbers: wrong statements can be identified with ease. PrimeFan 23:12, 3 March 2007 (UTC)

Hexadecimal
I saw a comment in the article source "TO DO: find or disprove hex# dihedral primes with 3 and E". E3 hexadecimal = 227 decimal is itself prime. —David Eppstein 17:53, 5 March 2007 (UTC)
