Some of the characteristic features are examined of four-jet production at hadron colliders given by QCD (2 → 4) subprocesses. It is found that the universal behaviour of parton scattering subprocesses - which is a good approximation for (2 → 2) subprocesses and to a lesser extent for (2 → 3) subprocesses - is violated more significantly in the case of the (2 → 4) parton scattering processes. Methods are suggested for testing if the four-jet data sample receives additional contributions from double hard parton scattering.
