I’ve been working on Puzzle 73 for months and have scanned everything up to prefix 14 from 1000000000000000000 to 14fffffffffffffffff.
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.
Fair point but you're assuming everyone brute-forces blindly. I’m not claiming miracles, just targeted work over time with filtered subsets and decent resources. Not all efforts cost millions when strategy and persistence are involved. If you know, you know.
It's fine, we might have different definitions for "everything".
