For certain finite groups G of B¨acklund transformations we show that the dynamics of G invariant configurations of n | G | Calogero–Painlev´e particles is equivalent to certain n -particle Calogero–Painlev´e system. We also show that the reduction of dynamics on G -invariant subset of n | G |× n | G | matrix Painlev´e system is equivalent to certain n × n matrix Painlev´e system. The groups G correspond to folding transformations of Painlev´e equations. The proofs are based on the Hamiltonian reductions.
