The reachable set in time T>0T>0, R(T){\cal R}(T), is here investigated for the symmetric control system x˙(t)=f(x(t))u(t)\dot x (t)=f(x(t))u(t), u(t)∈B‾u(t)\in\overline{B}. It turns out that, for f(x)f(x) smooth and nondegenerate, R(T){\cal R}(T) has finite perimeter, and a sharp estimate for the time-dependence of the perimeter and volume of such a set can be obtained.
