Abstract
For the Euclidean plane ℂ the Steiner mapping associating any three points a, b, c with their median s, and the corresponding operator PD of metric projection of the space l13(ℂ) onto its diagonal subspace D = {(x,x,x): x ∈ ℂ}, PD(a,b,c) = (s,s,s): s are considered. The exact value of the linearity coefficient of PD is calculated.
