The trigonic small stellated dodecahedron faceting, or tissidaf, is an orbiform polyhedron and, as its name suggests, an edge faceting of the small stellated dodecahedron. Its faces are 6 triangles and 6 pentagrams.

It appears as a cell of the great trigonal swirlprism and the great toroidal trigonal swirlprism.

Vertex coordinates[edit | edit source]

Its vertex coordinates are the same as those of the small stellated dodecahedron.
