Title: Compositions of Functions and Permutations Specified by Minimal Reaction Systems,
Abstract: This paper studies mathematical properties of reaction systems that was
introduced by Enrenfeucht and Rozenberg as computational models inspired by
biochemical reaction in the living cells. In particular, we continue the study
on the generative power of functions specified by minimal reaction systems
under composition initiated by Salomaa. Allowing degenerate reaction systems,
functions specified by minimal reaction systems over a quarternary alphabet
that are permutations generate the alternating group on the power set of the
background set.
