The 19-7 gyrochoron, also known as funky 19, is a convex isochoric polychoron and member of the gyrochoron family with 19 edge-laterostellated heptagonal prisms as cells. It can also be constructed as the 19-8 gyrochoron. It is also the heptagonal funk prism.
Each cell of this polychoron has bilateral symmetry, with 2 mirror-symmetric heptagons, 2 mirror-symmetric pentagons, and 6 kites for faces.
