The term IT COMES BEFORE PENTA is referring to the prefix 'tetra-', which means four. This prefix is derived from the Greek language and is used in many scientific terms, such as tetrahedron (a four-sided polyhedron) and tetrapod (an animal with four limbs). It is also used in chemistry to refer to molecules with four atoms or groups of atoms. In mathematics, it is used to refer to a group of four numbers or objects.
