Comparison of universal logic gates with NAND and NOR gates in the realisation of functions of three variables

This report furthers earlier work of, in particular, Hellerman, who catalogued the minimum number of NOR and NAND elements necessary to realise all 223 logic functions of three independent binary input variables. Here we consider the use of universal logic elements rather than NOR and NAND, and derive corresponding statistical and detailed information when the former are used for random logic purposes.
