The dodecaswirlic diacositetracontachoron, also known as the doeswirl 240, is an isochoric polychoron with 240 truncated pentagonal prisms as cells. It is the second in an infinite family of isochoric dodecahedral swirlchora.
Each cell of this polychoron has a chiral pentagonal prismatic symmetry with 2 pentambi (pentagonal-symmetric decagons), 5 rectangle-symmetric octagons, and 10 isosceles triangles for faces.
