In the cases of open sets and the system of partially non-intersecting domains, the solution of the extremal problem for the n-ray point system is obtained. The algebraic and analytical properties of the algebra of complex Segre quaternions are investigated. In particular, the Cauchy-Riemann conditions of differentiability of a function were written, besides that, in this algebra, a method of the solving of polynomial equations was developed.
