John Tromp from the Netherlands shows that from the 3^169 possible
colorings of a 13x13 board 8.66% of those positions are legal, which
corresponds to the amazing number of:
3724979230
7686396442
2949047670
2451767424
9157948208
7175332547
9955097059
5875237705
(80 digits).
Denis Feldman from France shows this number consists of two primes:
744995846
1537279288
4589809534
0490353484
9831589641
7435066509
5991019411
9175047541 and 5
which is pronounced Go in Japanese. Coincidence? I think so...
