Item 1 (expressing (p/q)! in terms of other (p/q)!) has no general solution still, as far as I know, but can easily be handled empirically for medium-sized n with the PSLQ algorithm.
Item 96 ("Solve go") can be made tractable by setting the board size to n=2.

At first I thought this was an "assume a spherical cow"-style joke, but no, it turns out there are 386 billion possible games you can play on a 2x2 Go board: http://tromp.github.io/go/legal19.html http://tromp.github.io/go/legal19.html
- conistonwater 9y agoI thought indeed that I was making a "spherical cow" joke. I was actually thinking of this: https://tromp.github.io/java/go/twoxtwo.html https://tromp.github.io/java/go/twoxtwo.html, so only 1446 nodes after pruning.
