I wonder what's the smallest Go board such that the number of legal positions is a legal position? (Not expecting an answer anytime soon.)

- tromp 11y agoMy previous writeup of the L18 result at https://web.archive.org/web/20150310085851/http://tromp.github.io/go/legal.html https://web.archive.org/web/20150310085851/http://tromp.gith... answers your question: "only L2, L3, L7 and L10 can be represented as legal positions themselves", graced with a picture of L10. L2=57 is 2010 in ternary, which looks like O . X .
- chch 11y agoIt seems like 2x2's 57 legal positions, which becomes 2 0 1 0 in ternary, is a legal position. :)
