A tiling is said to be fault free
if there are no straight lines which can split the tiling without intersecting a tile.
trivially form a fault free tiling of a 2x3 rectangle.
Find a fault-free tiling of a 9x5 rectangle using 15 L-triominoes.
Horrible stuck key!
This is the basic block I used to solve 'Tiling Trial' some time ago. Apparently it can also be done with 11 tiles.
