Are you suggesting they are not correct???

I have verified that the first 1,000 are prime. I ran it on a MacOS 300MHZ
Laptop and under the same with LinuxPPC - 30 seconds faster.
I ran it on a UltraSparc (production WWW server) took about 5 minutes...

Other test machines to follow:
300MHz MacOS Desktop,
333 "  Ultrasparc 10 (PCI) Desktop,
233 "  BeOS (Intel),
250 "  PPC (MacOS, BeOS, LinuxPPC) (I think it's an 8500,
            but I need to dig it out of the closet... :)

Keep ya posted,
