In this paper we study set mappings on 4-tuples. We continue a previous work of Komjath and Shelah by getting new finite bounds on the size of free sets. This is obtained by an entirely different forcing construction. Moreover we prove two ZFC results for set mappings on 4-tuples and also as another application of our forcing construction we give a consistency result for set mappings on triples.
