Hexagonal bipyramid bipyramid has a plane of symmetry (which is horizontal in the figure to the right) where the bases of the two pyramids are joined. This plane is a regular hexagon. There are also six planes of symmetry crossing through the two apices. These planes are rhombic and lie at 30° angles to each other, perpendicular to the horizontal plane. It can be drawn as a tiling on a sphere which also represents the fundamental domains of [3,2], *322 dihedral symmetry: The hexagonal bipyramid, dt{2,6}, can be in sequence truncated, tdt{2,6} and alternated (snubbed), sdt{2,6}: The "hexagonal bipyramid", dt{2,6}, can be
Hexagon (comedy show) selected each year. Recent recipients have included Sarah's Circle, the ALS Association, Hospice Caring, and the Wounded Warrior Project. Hexagon is supported by the affiliated Friends of Hexagon. As of 2014, Hexagon had raised over $3.5 million for charity. Hexagon has received recognition for its work in the Washington community.
