The digonal-triangular triswirltegum, also known as the hexagonal funk, is a convex isochoric polychoron and member of he duoprismatic swirltegum family with 18 identical cells. It is the simplest nontrivial duoprismatic swirltegum.
Each cell of this polychoron has bilateral symmetry, with 2 mirror-symmetric hexagons, 1 rhombus, 4 kites, and 2 isosceles triangles for faces.
