Theradical circle of theNeubergcircles hascircle function

l=(a^2b^4-b^4c^2+a^2c^4-b^2c^4)/(bc(a^2b^2+a^2c^2+b^2c^2)),
(1)

which does not correspond to any Kimberling center. The corresponding center is

alpha_(194)=(a^2b^2+a^2c^2-b^2c^2)/a,
(2)

corresponding to Kimberling centerX_(194), and its radius is

R_R=(sqrt(f(a,b,c)))/(a^2b^2+a^2c^2+b^2c^2),
(3)

where

f(a,b,c)=a^6b^4+a^4b^6-2a^6b^2c^2+a^4b^4c^2-2a^2b^6c^2+a^6c^4+a^4b^2c^4+a^2b^4c^4+b^6c^4+a^4c^6-2a^2b^2c^6+b^4c^6.
(4)

It isorthogonal to theStevanovićcircle, and no Kimberling centers lie on it.
