Mandak A.A construction weighted projective plane of order 9 and (2, 9 – 1)-quasigroupWe introduce a notion of weighted projective planes which is a generalization of usual projective planes. We prove that a Frobenius group G of order 20 operates on a projective plane P of order 9 as a colineation group. Using this operation the plane P may be constructed. A weighted projective plane P’ of order 9 is equivalent to a totally symmetric (2, 9 – 1) -quasigroup. To reports list |
