Some properties of 6-figures and cross-ratios in some moufangklingenberg planes

Abstract

In this paper, we study on Moufang-Klingenberg planes M(A) defined over a local alternative ring A of dual numbers. We get relations between some special 6-figures and its ratios. Also, we construct a relation between the solvability of the special quadric equation in A and the existence of the special 6-figure in M(A). Moreover, we give a construction which provides an algorithm for "squaring" and "cubing" a cross-ratio of points in M(A).
