The reactions pp → pf (X )ps, where X 0 is observed decaying to ππππ , ππππ and ππππ , have been studied at 450 GeV/c. There is evidence for an a2(1320)π decay mode of the η2(1645) and η2(1870) in the π πππ and ππππ final states. The f2(1950) is consistent with being a single resonance with a dominant f2(1270)ππ decay mode. The f0(1370) is found to decay dominantly to ρρ while the f0(1500) is found to decay to ρρ and σσ.
