# Abstract:

Two points a and b in a set S are said to be r-connected if there is a finite sequence of points a p0, p1,..., pn b with pi belongs to S and the distance rhopi, Pi1 plus or minus r, 1 0,..., n-1. In the paper the authors deal with palnar r-separating sets C whose removal from the plane R sub 2 r-separates two points a and b in R sub 2 - C. More precisely, the report discusses the structure of irreducible r-separating subset. Author
