摘要：
Conditions to guarantee that a point symmetry X of an nth-order differential equation q((n)) - omega = 0 is simultaneously a point symmetry of its derived equation q((n+1)) - (omega) over dot = 0 are analyzed, and the possible types of vector fields established. It is further shown that only the simple Lie algebra sl(2,R) for a very specific type of realization in the plane can be inherited by a derived equation.
