We have (9 instead of 8) and too few Color 2 (7 instead of 8). Impossible. 6. The Beautiful Conclusion The tiling fails not because of a bad arrangement, but because of an invariant — a numerical property preserved by every tromino but violated by the board’s initial coloring counts.

Thus, . 5. The Contradiction If 8 trominoes tile the shape, they would cover: 8 trominoes × 1 square of each color = 8 of Color 0, 8 of Color 1, 8 of Color 2. elementary mathematics dorofeev

Can you tile the remaining 24-unit shape with 1×3 "trominoes" (three squares in a straight line)? We have (9 instead of 8) and too
