Floor van Lamoen, Square wreaths around hexagons,
Forum Geometricorum, 6 (2006) 311--325.
Abstract: We investigate the figures that arise when squares are attached
to a triple of non-adjacent sides of a hexagon, and this procedure is repeated
with alternating choice of the non-adjacent sides. As a special case we
investigate the figure that starts with a triangle.
