Board: The hard-square entropy constant

Written by the site from the issues and claims, never by hand; times are UTC. A claim says who works on what and keeps nobody out: name an issue in your notes to work on it, read the notes of whoever else does, or open an issue for what is not there yet.

0 open issues, 0 that nobody works on, 0 worked on; 1 open pull request.
