The stellated decachoron or sted is the simplest regular compound polychoron, and the third in an infinite series of regular bi-simplex compounds. It is a compound of two pentachora in dual orientations. It has 10 tetrahedra as cells, with 4 cells joining at a vertex. As the name suggests, it is also a stellation of the uniform decachoron.
