64 tetrahedron grid is made out of 64 tetrahedrons each tetrahedron has 4 points so the 64 tetrahedron grid has 256 points
(64 tetrahedron grid)=(256 points)+(64 tetrahedron's)+(8 star tetrahedrons)=256+64+8=328(xen particle)
The 64 tetrahedron grid is a giant star tetrahedron
(64 tetrahedron grid)=(256 points)+(64 tetrahedrons)+(8star tetrahedrons)+(2(5 tetrahedral tetractys))+(7 tetractys)+(star tetrahedron)=256+64+8+70+28+18=444
