| Abstract: | Derived semifield planes admitting non trivial affine elations with more than one centre are examined in detail and several new examples of such plantes are constructed. A new characterization of the Hall planes of even order among derived semifield planes is also given.Research partially supported by G.N.S.A.G.A. (C.N.R.) |
