The main result shows that if $R$ is a semiprime ring satisfying a polynomial identity, and if $Z(R)$ is the center of $R$ , then card $R\,\le \,{{2}^{\text{card}\,Z\text{(}R\text{)}}}$ . Examples show that this bound can be achieved, and that the inequality fails to hold for rings which are not semiprime.
