Exact definition of a prene

Develop a precise, formal definition of a prene—beyond the informal description as “a basic unit of information that can be stored in physical things”—that specifies necessary and sufficient conditions under which a physical object stores a particular prene (i.e., constitutes a copy), and clarifies the boundaries of the concept for use in a general theory of evolution.

Background

The book introduces prenes as fundamental units of information underlying genes, memes, and Turenes, intended to unify biological, social, and computational evolution. While an informal, OED-like description is offered, the author explicitly acknowledges the lack of an exact definition and connects this limitation to deep issues such as the problem of universals.

Later, a set-theoretic approach (“What is a prene – really?”) is proposed to make the concept more amenable to research, but it is still described as not exact, reinforcing that a fully precise definition remains unresolved.
