That’s not true. I’ve been working on Puzzle 73 for months and have scanned everything up to prefix 14 from 1000000000000000000 to 14fffffffffffffffff. Higher puzzles like 71+ are absolutely being searched, even if they haven’t been solved yet.

You know how it goes, share too many details and in 2 minutes someone calls you a liar anyway 😉
Let’s just say it took time, decent firepower, and good software. If you know, you know.
Seems as everyone and their dog is a crypto genius these days, breaking boundaries this or that as easy as a weekend barbecue.
Needless to say, what you claim as having done has an identical problem size as P71, and requires at a bare minimum a few million $ to accomplish. If you know, you know this is why people like Bram won't bother with 71+ for quite some time. Going after 71 and up is simply throwing money out the window today.
