Sorry, but how did you compute this? Do you know that there are less than 10^85 board positions which have a symmetry?

- tromp 11y agoThe bulk of symmetric positions are those with 180 degree rotation or reflection symmetry, and there are at most 3^{10x19} of those (I had mistakenly bounded it as 3^180). So it's actually less than 10^90, meaning that L19/8 is correct in the first 80 digits.
