%N Numerators of rationalvalued radii of circles given by 3 distinct integer points in the euclidean plane.
%C A triangle in the Euclidean plane defines a circumcircle. There exist only certain rationalvalued circumradii if the vertices of the triangle have integer coordinates. They are rendered by the pair of sequences A128006/A128007 in increasing order.
%Y See A128007 for denominators.
%Y Cf. A128008, A128009, A128010, A128011, A192493, A192494.
