It can have one, two or three pairs of parallel faces.
An octagonal prism has a total of 5 pairs of parallel faces. It has two parallel octagonal bases and eight rectangular lateral faces, with each rectangle having a parallel counterpart on the opposite side of the prism. Thus, the pairs of parallel faces consist of 1 pair for the octagonal bases and 4 pairs for the rectangular faces.
