## Abstract Arithmetical definability has been extensively studied over the natural numbers. In this paper, we take up the study of arithmetical definability over finite structures, motivated by the correspondence between uniform AC^0^ and FO(PLUS, TIMES). We prove finite analogs of three classic r
