I have been keeping such a list and was going to offer up all my
findings once I have found my next brilliant number. The program I used
to do the "sieving" was Miracl's factor.exe (slightly modified by me)
and it does some ecm to remove up to 25 digit factors. So, would my
list be too sparse to be useful? I didn't keep any of the sieved
numbers, but everything that fell through that I have nfsx or ppsiqs
I was also thinking of giving the timings for the work thus far, and
maybe also giving a list of the primes that were found in this range.
Would either of the last two pieces of information be useful to anyone?
I'm still compiling the information and still waiting for the next
brilliant, but as soon as both are ready I'll e-mail the list.
