The primary purpose of this paper is to show that infinitesimal velocity-dependent symmetry mappings ((a) x-bar/sup i/ = x/sup i/ +deltax/sup i/, deltax/sup i/ equivalent xi/sup i/(x,x,t)deltaa with associated change in path parameter (b) t-bar = t+deltat, deltat equivalent xi/sup 0/(x,x,t)) of classical (including relativistic) particle systems (c) E/sup i/(x,x,x,t) = 0 are expressible in a form with a characteristic functional structure which is the same for all dynamical systems (c) and is manifestly dependent upon constants of motion of the system. In this characteristic form the symmetry mappings are determined by (d) xi/sup i/ = Z/sup i/(x,x,t) +x/sup i/xi/sup 0/,xi/sup 0/ arbitrary; the functions Z/sup i/ appearing in (d) have the form (e) Z/sup i/ = B/sup A/g/sup i//sub A/(C/sup 1/,...,C/sup r/; t), 0< or =r< or =2n, A = 1,...,2n, where the B/sup A/ are arbitrary constants of motion and the C's appearing in the functions g/sup i//sub A/ are specified constants of motion.
