This officially gives omniperiodicity, since we have oscillators of all periods below 18 from soup

How do I allow more threads to be used?

Edit: Cygwin does not support multithreads. I have no idea what compiler can though.

Try using WSL. Running apgsearch multithreaded on WSL works for me.

The key question is: what is the smallest set of tracks necessary to reconstruct a (hypothetical) helix? Most self-supporting spaceships start with a small set of tracks that they then use to build new ones. 1. In order to build new tracks, we have two options: either we use a kickback (so we need t...
