A strongly universal cellular automaton on the heptagrid with seven states

TL;DR

This paper presents a new strongly universal cellular automaton on the heptagrid with only seven states, improving previous models that required ten states, and maintains rotation invariance.

Contribution

The paper introduces a more efficient seven-state strongly universal cellular automaton on the heptagrid, reducing the number of states needed from ten to seven.

Findings

Successfully constructed a seven-state automaton that is strongly universal

Automaton is rotation invariant

Improves upon previous ten-state automaton

Abstract

In this paper, we prove that there is a strongly universal cellular automaton on the heptagrid with seven states which is rotation invariant. This improves a previous paper of the author where the automaton required ten states.
