For numbers in that range with the amount of effort applied, we would expect about 50% to have factors found. So the fact that no factor was found is about what one would expect from a coin flip. If you think that no factor found with 50 bits of factoring and a little bit of P1 makes your number more likely to be prime, then you are delussional.

What is my delusion here? That said, the odds of prime increase from, say, 1 in 4 million to 1 in 2 million via trial factoring; an additional bit of TF work might change "1 in 2 million" to "1 in 1.96 million" odds. tuckerkao is delusional if he thinks TF is evidence of a prime on this we agree. But it does improve the odds, no?

well until you get to the TF square root, then it is 100% sure that it is prime.

The LL test already showed that M103,374,163 was a composite. The unknown is currently on M103,674,163, I've tried several numbers with 1 digit modified by +3 or 3, frequently resulted in no factors as the parallelized twin fate numbers.

Also, so what? Seems the second half of my post sailed right over your head. Trial factoring is a nice way to filter out obviously composite numbers. Survivors of TF at this size are still at least a 2milliontoone shot against being prime. When you claim that TF finding no factors is something that helps your claims, you are demonstrating that you don't understand what trial factoring does. Also, why did you quote me? I asked where my reasoning was wrong, not where YOUR delusion was; though I'm glad, I guess, that you repeated your delusion when I asked where mine was.

NFPM1 for M103,674,163 as what I expected since yesterday, coin flips shouldn't be so predictable, thus PRP for M103,674,163 should have a composite residue although I haven't tested it yet.

Well, man, hat off, , despite out argument, I have to stay by your side in this one. At least you were/are doing some work to test your own predictions, albeit the predictions themselves are aberrant. So, I like your optimism, keep on testing!
This is contrary to other crackpots here who come with silly theories/numerology and do no work, expecting us to do their work. So, reserve this one and test it, same as you tested the other one, and we are friends forever...

My very first LL test was of M103,374,163 which is part of the prime trio with M103,374,113 and M103,374,133
M103,377,103 and M103,377,143 and M103,377,193 is a prime trio. https://www.mersenne.org/report_expo...3377193&full=1 After I finished the PRP tests of M103,377,103 and M103,377,143 with the composite residues, Kriesel still suggested me to run P1 factoring on these exponents. I ran the P1 factoring on another lookalike prime trio(M103,737,103 and M103,737,143 and M103,737,173), all 3 returned NFPM1 as what I've expected. https://www.mersenne.org/report_expo...3737173&full=1 Last fiddled with by tuckerkao on 20210114 at 22:27

For each of those 3, the P1 testing (with the settings you used and prior TF) should have factor about 4.64.7% of the time. Which means that for any 3 similar numbers in that rough range that are tested the same way, about 14% of the time you might find a factor (less actually, but that is a side point). So, this being 1 of the 86% of the time that no factor was found really does not mean much. You are delusional.
