Epiphainein counts unreachable single-side pawn diagrams (in chess) where pawns can move forward or diagonally-forward without limit whilst remaining on the board. Epiphainein is a serial calculation and takes a few seconds to calculate the number of unreachable diagrams on a regular 8 x 8 board. With a decent machine it should take roughly 4 hours to calculate the same on a 10 x 10 board.
