Whoa! This was a first hole, so it allegedly had a full t55 of ECM run on it. The probability that this P48 would survive a t55 is about a thousandth of a percent. Bob, is there any way to check whether the other holes in the 5-2 table received their appropriate ECM?

I ran 5,2,- a long time ago. It is likely that it was not among the first holes at the time I ran it. I no longer have that data. It was "left behind" on my office computer when I retired from work. [as was a lot of other data].

There is no way that I could have missed a p48. I ran 2000 curves with B1 = 1G and B2 = 9e13.

To be specific, you did the 5-2 table some time between October 9, 2018 and January 7, 2019 (according to your email), so just about within the last year. This particular number, 5-2,365 has been a first or second hole since September 13, 2016.

I guess it'll just be a mystery how this factor got missed.

[QUOTE=R.D. Silverman;530044]There is no way that I could have missed a p48. I ran 2000 curves with B1 = 1G and B2 = 9e13.[/QUOTE]Hmm. The P48 is indeed a factor of 5-2,365. I checked.

So, if there's no way you could have missed it, you [i]didn't[/i] miss it. Why were you holding out on us?
:-D

The only logical alternative I see here is, you didn't really mean there was "no way" you could have missed it. Given the fact that you [i]did[/i] miss it, obviously there [i]is[/i] a way.

Assuming the input was correct and the program worked as intended, the only way is that this particular P48 "beat the odds." How long those odds were, I do not know, but I assume the probability of non-detection wasn't 0.

Other possibilities include incorrect input (say, a typo, which would be my first guess if it had been me doing the typing), a programming error ("bug"), a compilation error, and a hardware error.

It should be obvious to anyone reading this thread that "missed it" refers to being
missed by ECM trials.

It was not missed. It was simply never run. To be an "ECM miss" would require that it
was run.
