Among the 268 possible tilings of a 12 x 12 square, there are 24 special tilings which are called
core tilings.
The set
of tilings reachable from the core tiling 1423 will be called
cluster 1423, as shown below.
The tiling that is colored in blue is the core tiling.
Note that the vertices are colored according to the distance to the core.
