Streszczenie
Pairs of functional pre-Schröder equations ($S_n$) are considered. We show that under some assumptions the system of two equations $(S_3)$, $(S_n)$ for some $n\geq 4$ is equivalent to the system of all equations $(S_n)$ for $n\geq 2$. The results answer a question of Gy. Targonski [5] in a particular case.
