A remark on graph operators

A theorem is proved which implies affirmative answers to the problems of E. Prisner. One problem is whether there are cycles of the line graph operator L with period other than 1, the other whether there are cycles of the 4-edge graph operator 4 with period greater than 2. Then a similar theorem follows.
