%N A201269 Coordinates y of points {x,y} of Mordell elliptic curves x^3-y^2 for primary extremal points with quadratic extensions over rationals.
%C A201269 For x coordinates see A201047.
%C A201269 For distances d between cubes and squares see A201268.
%C A201269 For successive quadratic extensions see A201278.
%C A201269 Theorem (*Artur Jasinski*):
%C A201269 Every particular coordinate y contained only one extremal point.
%C A201269 Proof (*Artur Jasinski*): Coordinate x is computable from the formula x(y) = round(y^(2/3)) and distance d between cube of x and square of y is computable from the formula d(y) = round(y^(2/3))^3-y^2.
