For a finite groupGand a finite setA, we study various algebraic aspects of cellular automata over the configuration space. In this situation, the setof all cellular automata overis a finite monoid whose basic algebraic properties had remained unknown. First, we investigate the structure of the group of unitsof. We obtain a decomposition ofinto a direct product of wreath products of groups that depends on the numbersof periodic configurations for conjugacy classes [H] of subgroups ofG. We show how the numbersmay be computed using the Möbius function of the subgroup lattice ofG, and we use this to improve the lower bound recently found by Gao, Jackson and Seward on the number of aperiodic configurations of. Furthermore, we study generating sets of; in particular, we prove thatcannot be generated by cellular automata with small memory set, and, when all subgroups ofGare normal, we determine the relative rank ofon, i.e. the minimal size of a setsuch that.
