The hexagonal yod/cube of the tetractys is the 12 vibrational dimensions and the hexagonal yod/cube is 1+2+3+4+5+6=21 and 21 forms the 231 gates and the 231 gates is related to the 441 cubistic matrix(As talked about above).

The 231 gates is the E8 lie group(120 cell)/64 tetrahedron grid and the 64 tetrahedron grid is encoded in the cubistic matrix(120 cells) also whats interesting is that the 64 tetrahedron grid has 144 faces making up its outside and two Tetragrammatons is 72+72=144 and the Tetragrammaton is the tetractys and two tetractyses forms the fruit of life which encodes two star tetrahedrons which encode all vibrational dimensions and the fruit of life encodes Metatrons cube which is the 64 tetrahedron grid so all vibrational dimensions are encoded in the 64 tetrahedron grid which corresponds its 144 faces to the vibrational dimensions since there are 144 sub-dimensions. This shows 144, 441, 21 and 12 all have a very interesting connection as shown here since there are 12 vibrational dimensions.

The last line of pascals triangle tetractys is 1331 which as shown in previous posts is also related to the 231 gates/E8 lie group/64 tetrahedron grid.
