If you are dealing with a pair of primes, it seems (or seemed) to me that you are talking about the second paragraph in http://jsoftware.com/pipermail/programming/2013-May/032541.html which reads "Since both p & q (> 2) are prime, their sum is an even number and not prime, but could the half of their sum be a prime?" I can see that 2 is a valid p for the question posed in the first paragraph, and that 3 is the corresponding result, but with your above description you are examining a quarter of the sum of two primes and not half the sum of two primes. Re-reading a number of posts in this thread, I now see that your "hpp" was indeed a different subject from the subject I thought I was writing about. So that is the answer to my question - we were indeed talking about different subjects. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
