Given 3 points abc there exist 6 permutations or shuffles: abc, acb, bac, bca, cab, and cba. Given 2 points a and b, there exist only 2 shuffles: ab and ba. Both these 2p and 3p shuffles hide two distinct directional invariance properties, say the left (L) and the right (R) property. For the 2p configurations, ab indicates direction to the right and ba direction to the left. For the 3p configurations, abc, bca, and cab indicate direction to the right, while acb, bac, and cba to the left. In these cases, linearity implies one dimensionality and for all 1-dim shuffling configurations there exist two and only two directional invariance properties: L and R. For 4p 1-dim shuffles, there exist 24 configurations: abcd, abdc, acbd, acdb, adbc, adcb, bacd, badc, bcbd, bcda, bdac, bdca, cabd, cadb, cdad, cbda, cdab, cdba, dabc, dacb, dbac, dbca, dcab, and dcba. Among these there are 4 4-cycles of R: abcd, bcda, cdab, and dabc. There are 4 4-cycles of L: adcb, badc, cbad, and dcba. However, there are 10 2-cycles of both R and L: abdc, acbd, bacd, bdac, cabd, cdba, dacg, dbac, dbca, and dcab. On the other hand, there are 3 2-cycles of L: acdb, bdca, and cbda. There are also 3 2-cycles of R: adbc, bcad, and cadb.
These imply that the number of directional invariance properties (Q) is directly proportional to the double exponential growth of the dimension: Q=2ͩ where d denotes the dimension. Excluding d=0, for d=1, Q=2; d=2, Q=4; d=3, Q=8; d=4, Q=16; d=5, Q=32; d=6, Q=64; d=7, Q=128; d=8, Q=256. For d=2, the Q’s are derived from L, R, F (forward), B (backward): LF, LB, RF, and RB. For d=3, the 8 Q’s are derived from: L, R, F, B, U (up), and D (down): LFU, LBU, RFU, RBU, LFD, LBD, RFD, and RBD. By these, the dimensional shuffles is defined as the product of Q and the point factorial.
