Triakos
Triakos is a term that can refer to several different concepts, most commonly in mathematics and astronomy. In geometry, "triakos" might be used as a prefix or part of a name for a shape or object related to the number thirty. For example, a triacontahedron is a polyhedron with thirty faces, though this is not a standard or widely used term in formal geometric nomenclature. More common polyhedra with thirty faces include the rhombic triacontahedron, which is a convex equilateral polyhedron.
In astronomy, the term "triakos" could also appear in the names of celestial objects or phenomena, again
