Since the F function need not be reversible, there is no need to construct an inverse s-box for decryption and S-boxes of any size may be used.

The permutation ensures rapid avalanche; a one-bit change in key affects one s-box; a one-bit change in the input block affects one or two s-boxes.

With the permutation, changing the output of one s-box affects several in the next round.

There is no expansion from 32 bits to 48, so s-box inputs are only four bits rather than six, and there is no permutation of the output bits, only an 11-bit circular shift; these differences make GOST easier to implement in software than DES.
