What are all the possible subdivisions of the P3 tetrahedron (i.e. for each face, 3 vertices plus two points per edge, located at 1/3 and 2/3, and the centroïd of the face, so a total of 20 points for the tetrahedron), by P1 tetrahedrons ? Or could someone give some reference, where it has already be done ?

If you do the "obvious" thing of forming P1 tetrahedrons similar to the original tetrahedron whenever possible, you end up making a P1 for each of the original 4 corner vertices, and a P1 for each of the middle segments of the 6 edges. The remaining volume is 4 similar octahedrons. You can apply any tetrahedralization of an octahedron to split them up (e.g. into 4 tets circling around one diagonal), or you can add a vertex in its center and make 8 tets that emanate from the central vertex (these may be more nicely shaped).
