A strongly universal cellular automaton in the dodecagrid with five states (2104.01561v2)
Published 4 Apr 2021 in cs.DM
Abstract: In this paper, we prove that there is a strongly universal cellular automaton in the dodecagrid, the tessellation {5,3,4} of the hyperbolic 3D-space, with five states which is rotation invariant. This improves a previous paper of the author where the automaton required ten states.
