The small dihectotetraconta-trihectohexaconta swirlprismatic hectoicosa-trihectohexacontachoron, abbreviated as the small 240-360 swirlprismatic 120-360choron or simply sidditsphit, is a nonconvex uniform polychoron. It is made out of 360 tetrahedra, 480 triangular prisms in two different types, and 240 tetrahemihexahedra.

Along with the great dihectotetraconta-trihectohexaconta swirlprismatic hectoicosa-trihectohexacontachoron, it is one of the first two new uniform polyhedra to be discovered since 2006. It was found by _Geometer, a member of the Hi.gher Space forum.
