Let me add that the APL finds ALL solutions, no rotations or symmetries,
and written to print out on a typewriter. Somewhere in the code I think I
have page width (quad PW), so that as many solutions as possible print
across the page. Further you get a picture of the board, not just
coordinate pairs.
I'll make no attempt to get this to the forum.

Interesting.
A J one-liner (transcribed, almost literally, from that explicit
solution in the J
wiki) was significantly shorter.
