#### Abstract

Let {Sj:1≤j≤3} be a set of three contractive similarity mappings such that Sj(x)=rx+j−12(1−r) for all x∈R, and 1≤j≤3, where 0

Previously, Roychowdhury gave an exact formula to determine the optimal sets of *n*-means and the *n*th quantization errors for the standard triadic Cantor distribution, i.e., when r=15">r=15r=15. In this paper, we further show that r=r0">r=r0r=r0 is the greatest lower bound, and r=r1">r=r1r=r1 is the least upper bound of the range of *r*-values to which Roychowdhury formula extends. In addition, we show that for 00
