Extract

Improved sufficient conditions are developed for the functional completeness of a set F of functions with variables and values ranging over N = {1, 2, …, n}, where n ≥ 3. In particular, F is complete if it generates a triply transitive group of permutations of N and contains either (i) only a single function, or (ii) at least one function satisfying the Slupecki conditions, the latter apart from certain exceptional cases. These are shown by a detailed investigation to occur only when n = 3 or when n is a power of 2 and all functions of F are linear in each variable, relative to some representation of N as a vector space over Z2.
