: a(10) was discovered today by Amiram Eldar (the author of the [https://oeis.org/A318646 A318646] sequence) for m = 3208386195840. -- [[User:Trizen|Trizen]] ([[User talk:Trizen|talk]]) 12:10, 4 June 2019 (UTC)
Yep, knowing that, I've now found a(10) to be:
24616075028246330441656912428380582403261346369700917629170235674289719437963233744091978433592331048416482649086961226304033068172880278517841921
So my 16 billion wasn't even in the right ballpark and I estimate it would have taken my Go program about 8.5 days to find it, albeit on slow hardware. On a fast machine, using a faster compiler and GMP for the big integer stuff, you might be able to get this down to a few hours but it's probably best to remove it as an optional requirement as I see you've now down. Interesting task nonetheless so thanks for creating it. --[[User:PureFox|PureFox]] ([[User talk:PureFox|talk]]) 15:03, 4 June 2019 (UTC)
