## Abstract

We consider the computational power of constant width polynomial size cylindrical circuits and nondeterministic branching pro-grams. We show that every function computed by a $II_2\hspace{2mm}{\circ}\hspace{2mm}MOD\hspace{2mm}{\circ}\hspace{2mm}AC^o$ circuit can also be computed by a constant width polynomial size cylin-drical nondeterministic branching program (or cylindrical circuit) and that every function computed by a constant width polynomial size cylin- drical circuit belongs to $ACC^{\circ}$.
