The SHORT answer to your question is no. The contrary is true. Almost all of those numbers (a mathematical term) are composite. I suggest you try the Prime pages of Chris Caldwell which hold a wealth of information. Try this link for more on those numbers which are called "primordial +1 primes" or "prime factorial". These are the only numbers of that form that have been discovered for 2>p>35000....p#+1 is prime for the primes p=2, 3, 5, 7, 11, 31, 379, 1019, 1021, 2657, 3229, 4547, 4787, 11549, 13649, 18523, 23801, and 24029 > http://www.utm.edu/research/primes/glossary/PrimeFactorial.html > [EMAIL PROTECTED] wrote: > Hello, > > Just wondering if someone can give me a yes or no on a simple concept. > > Given {1, 2, 3, 5, 7, ..., Xn-1, Xn}, where each Xn is prime and there are > no prime numbers between each Xn-1 and Xn, is the following always prime: > > (1*2*3*5*7*...*Xn-1*Xn) + 1 > > Thank you! > > -- > ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ > : WWW: http://www.silverlink.net/poke : Boycott Microsoft : > : E-Mail: [EMAIL PROTECTED] : http://www.vcnet.com/bms : > ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ________________________________________________________________ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm
