The 15-4 gyrochoron, also known as the triswirl 15, is a convex isochoric polychoron and member of the gyrochoron family with 15 paratetratruncated rhombic prisms as cells.
Each cell of this polychoron has chiral digonal prismatic symmetry, with 2 rectangular-symmetric hexagons, 4 mirror-symmetric hexagons, and 4 isosceles triangles for faces.
Compared to other gyrochora with 15 cells, this polychoron has reflective doubled symmetry, because 15 is a factor of 42-1 = 15.
