[QUOTE=gd_barnes;214975]Even better news:

I just ran PFGW 3.3.4 against 195 composite PRPs that I had previously found for k<22M for Sierp base 63 using PFGW 3.3.2. As verified by other software, it correctly reported back 132 primes and 63 composites. All composites were n<5. All primes were n>=14; some as high as n=~190.

New testing in the k=22M-30M range is coming back with only composite PRPs for n<5. Testing with other software confirmed that they are all composite; consistent with all composites for n<5 for k<22M.[/QUOTE]

Gary, please post or send me the ones that were in error in 3.3.4. I'll look into them. I might just force -a1 on primality tests when n is really small. It should have a negligible affect on primality testing. I'll decide once I see the list.

What errors? No skimming of postings please. Please reread the entire post #192 again. Would I have said "nice work" in the next-to-last para. if there were still errors? :-)

I clearly misunderstood what you wrote. To me, there were a couple of possible interpretations (because of how the message was worded). Now that I'm taking more time to understand what you wrote in my own way.

Let me know of this interpretation is correct:

You have a list of 195 numbers. 132 are prime and 63 are composite (proven with other software). A PRP test with PFGW 3.3.2 output all 195 of those numbers as PRP. A primality test with PFGW 3.3.2 indicated that all 195 were composite. A PRP test with PFGW 3.3.4 returned correct results for all 195 numbers (132 PRP, 63 composite). A primality test with PFGW 3.3.4 also returned correct results for all 195 numbers (132 prime, 63 composite).

The 63 composites all had n<5 while the 132 primes had n>=5.

If I didn't understand this correctly, let me know.

That is correct.
