Is there any algorithm to compose a sequence of logical operations equivalent to 16 bit S-box? If yes, what would be the length of resulting sequence? e.g. for 8 bit S-box equivalent boolean logic operations sequence's length is ~20 ops...
Upd: Found it: 16 truth tables derived from S-box table, swap memory method (SMM), then Quine McCluskey algorythm.
