  We prove a finiteness result for the systolic area of groups, answering a
question of M. Gromov. Namely, we show that there are only finitely many
possible unfree factors of fundamental groups of~2-complexes whose systolic
area is uniformly bounded. Furthermore, we prove a uniform systolic inequality
for all 2-complexes with unfree fundamental group that improves the previously
known bounds in this dimension.
