Order of dimensions
When I created the original form of this page, I probably decided that n in n×m stands for the number of rows based on the convention for matrices. Now I wonder if that was a mistake, since MoHex (and also KataGo) will interpret n in "boardsize n m" (which changes the size to n×m according to Hex: Passing on the Torch) as the number of columns. The matrix convention also doesn't match our use of board coordinates: "c" in "c2" determines the column.
So, rather than attempting to fix GTP by claiming boardsize n m changes the board size to m×n, I think changing Parallelogram boards and other pages that followed its(?) convention might be the better solution. --Wurfmaul (talk) 06:48, 24 January 2023 (UTC)
