On the Quartic Developable

The quartic developable is generated by the tangents of a twisted cubic. Taking the cubic as

x = t³, y = t², z = t,w = I,                                             (I)

the equation of the developable is

f(x,y,z,w)=6xyzw-4y³w-4xz³+3y²z²-x²w² = 0.                  (2)

The object of this paper is to obtain a remarkable property regarding the first polar surfaces of this developable.
