COMMENTS
The shape for this sequence attempts to find a connection between the unique geometry of the sphinx tile and a polymerization process.
The number of tilings of a stackable sphinx tiled shape has previously been described A287999.
In contrast to the stackable shape this shape is interlocking.
This shape has one female and three male parts.
The properties of this shape that inhibit different polymerizations are noted.
The various polymer configurations from a central nucleus are shown.
