An exception to the general rule that all the LCAU automata are one dimensional has been made for some of the binary automata with larger neighborhoods. The programs are basically one dimensional. On the one hand the neighborhood sizes are inconveniently large, especially for the de Bruijn and ancestor menus; on the other, the volume of the neighborhood coincides with that of various higher dimensional automata whose statistics are interesting.
As a consequence, programs such as and have been set up to concentrate on the probability menu, even though the other menus function partially or not at all. Beginners may simply want to use the REC demonstration, ignoring the rest of the program.
