Bis [2] introduced the notion of entropy-like invariants as an extension of the concept of pointwise preimage entropy.This paper follows Bis concept and extends the behaviour of preimag eentropy to the case of a fixed sequence of maps.Therefore, some results are obtained, and we also show that for any continuous maps S and T from a compact metric space on to itself, the maps S o T and T o S have the same pointwise preimage entropy.
