The Professor Pyraminx is the 5x5x5 version of the Pyraminx puzzle. Similarly to how the Rubik's Professor's Cube is the 5x5x5 version of the original Rubik's Cube.
Each face of the Professor Pyraminx consists of 25 triangles (compared to 9 in the Pyraminx and 16 in the Master Pyraminx) making it a much harder puzzle to solve. As in other Pyraminx puzzles, the tips of this puzzle are considered "trivial" and have only 3 possible positions each. Solving each tip is in the worst case 1 move.
Since this puzzle is not an official WCA puzzle, there is no official record for fastest solve. However the unofficial record belongs to Canadian Louis Cormier and is 1:24.95 minutes.
