PUZZLE #4526: Coordinate Lattice (diff 7)

lattice learn difficulty: 7/7 reason author: system unsolved

An 8x8 grid maps coordinates to letters. Follow the coordinates to decode the password.

DATA

Grid	`['A', 'R', 'M', 'S', 'N', 'U', 'G', 'R'], ['A', 'R', 'N', 'O', 'H', 'P', 'L', 'A'], ['Y', 'V', 'U', 'C', 'I', 'O', 'E', 'O'], ['_', 'O', 'P', 'D', 'O', 'D', 'Y', 'A'], ['Z', 'M', '_', 'A', 'W', 'Y', 'Y', 'P'], ['K', 'L', '_', 'N', 'O', 'M', 'Q', 'E'], ['W', 'T', 'P', 'C', 'H', 'B', 'U', 'T'], ['X', 'A', 'C', 'T', 'C', 'O', 'G', 'M']`
Coordinates	`[2, 5], [2, 4], [0, 7], [3, 2], [4, 1], [6, 1], [5, 1], [1, 3], [0, 4], [1, 2], [3, 4], [5, 7], [4, 5], [6, 7], [6, 6], [3, 5], [1, 5], [5, 2], [3, 6], [0, 3], [1, 1], [0, 1], [1, 4], [2, 3], [7, 2], [2, 2], [7, 1], [4, 2], [2, 7], [3, 0], [0, 6], [2, 6], [5, 4], [0, 0], [1, 0]`
Size	`8`
Order	`shuffled`
Hint	`Map each [row, col] coordinate to its cell in the 8x8 grid. Coordinates are shuffled. The answer may contain underscores which represent spaces.`
Answer Format	`integer coordinate pair: x,y (e.g., "3,7")`
