theory about Descartes's xyz factorial researching

[dock]

Descartes have six characters: +x -x +y -y +z -z

Combine with factorial:

{+x-x+y-z+z-z} = 6! = 720

720 = 10 x 72

splitting group {+x-x+y-y+z-z} = 4 + 6:

Limited space of universe: 72 x 4 = 288, 288! = 7,196 x 10^584

+x+y+z-x-y-z = 72
+x+y-z-x-y+z = 72
+x+z-y-x-z+y = 72
+y+z-x-y-z+x = 72

Limited time of space: 72 x 6 = 432, 432! = 4,272 x 10^952.

+x-x+z+y-y-z = 72
+x-x-z+y-y+z = 72
+x-x+y+z-z-y = 72
+x-x-y+z-z+y = 72
+y-y-x+z-z+x = 72
+y-y+x+z-z-x = 72
