Universality has always played a major role in every branch of science. In particular, universality in cellular automata (CA) and computational systems has been explored extensively, especially the elementary CA (ECA) rule 110 and its properties. Instead of considering universal rules, one may think of universal functions that, when applied to the cellular automaton net, generate every CA. This approach asks that one imagine the cellular automaton net as a functional space whose values are determined by means of the conjectured function and its parameters. Following this idea, different functional parameters should generate different CAs. This universal function, the iota-delta function, has been proved to exist and is defined as follows:
