A characterisation of the tangents and generators of this quadric when q is odd has been proved by de Resmini [15], and we give an alternative using our result. © 2013 János Bolyai Mathematical Society and Springer-Verlag Berlin Heidelberg.en© 2013 Janos Bolyai Mathematical Society and Springer-Verlag Berlin HeidelbergA characterisation of the planes meeting a non-singular quadric of PG(4,Q) in a conicJournal article002013042410.1007/s00493-013-2402-70003211159000022-s2.0-8487978536118839
