This pattern came about by elaborating a loop of interleaved triangles and squares. Each of the six loops on the outside of the central hub comes of a loop of squares and triangles where three of the triangles have been replaced with hexagons. The hexagons introduces spaces in the loops so that they can easily be connected (with squares) to one another while maintaining the original angles of the replaced triangles. As well, there are additional hexagons put in the central hub to make the negative space more eye catching.
