Taking together the comments
"Pritchard mentions in CECV a game with a similar topologically-pentagonal but geometrically-"doubling" board."
from this thread and
"Pritchard's CECV lists a game "Xyrixa Chess" by David Samuel c.1980 played on this same board (provided I'm reading correctly)."
from the .comments on Tetrahedral Chess, it seems that some Chessboards are more obvious to those who devise Chess variants than we realise when we think of them. Xyrixa is certainly a shorter word than Tetrahedral to describe the 3d geometry with 12 Rook and 6 Bishop directions, and if it is the older name for that geometry perhaps I should use it in place of Tetrahedral in Man and Beast. It would be interesting to know what Mark Thompson thinks. I will however retain the current name for Tetrahedral Shogi, not just because changing the display on search pages takes so long but because it was genuinely inspired by Mr. Thompson's game. Does Xyrixa have any prior meaning, or did Mr. Samuel coin it specifically for the variant?
