The algorithms for generating the permutations

Collect all the representative shuffles for branches of length (4,6,8,10,12,14,16)

The models for evaluating GFS with all shuffles

Mount all the representative shuffles into GFS and evaluate their resistance on Differential, Linear, Impossible Differential, Zero Correlation, Integral, and DS-MITM attacks.
