The multiplicad is a simple example of an idea like the ruliad. It consists of a rulial multiway system based on the positive integers in which the
rules simply multiply by successive integers via
(Wolfram 2021). While
this multiplicad is presumably not capable of producing a full ruliad
on its own, changing the underlying rules (likely by just inserting the operation
of addition) might produce a system that is capable
of universal computation and which could therefore
generate the full ruliad (Wolfram 2021).
