C2, C3 as the diagonalpoints, and C as the originalpoint associated with the cubic.That the cubic associated withC in this new transformation isidentical with the original cubicfollows from the following consideration: The points B beingpoints of tangency count for eight given points.… … Fig. 79. CURVES OF THE THIRD ORDER. 193 at least twelve points in common with the original cubic, and isconsequently identical with it. In this new Steinerian transformation construct the point Dcorresponding to C. Then take the new quadruple CCXC2C3 andconstruct the associated cubic in the…
