In this work derivation of accurate estimate the production inner radius non-overlapping domains and open set. The problems arise such type in the �rst time in work [1]. It is late result this work generalize and
strengthen in works [2 { 13]. In works [7, 8, 10] introduce the general
systems points, the name n-radial systems points. In this work a success
the draw generalize some results the work [7
