In this paper we prove that there are only two different classes of central configura-
tions with convenient masses located at the vertices of two nested regular tetrahedra:
either when one of the tetrahedra is a homothecy of the other one, or when one of
the tetrahedra is a homothecy followed by a rotation of Euler angles =
= 0 and
= of the other one.
We also analyze the central configurations with convenient masses located at the
vertices of three nested regular tetrahedra when one them is a homothecy of the
other one, and the third one is a homothecy followed by a rotation of Euler angles
=
= 0 and = of the other two.
In all these cases we have assumed that the masses on each tetrahedron are equal
but masses on different tetrahedra could be different.^^^^
