Sažetak
In this paper it is proved that the curve of fourfold foci in the pencil of circular and rational cubics, which is deduced by ordinary inversion, is a circle, and its construction is shown. An analogus foci circle f is constructed in one pencil ({k_i}^3) of circular cubics of 1st genus. It is shown that by means of this circle focus of any cubics belonging to ({k_i}^3) can be obtained.
