Abstract

The projective linear group PGL(C,4) acts on cubic surfaces, considered as points of PC19. We compute the degree of the 15-dimensional projective variety defined by the Zariski closure of the orbit of a general cubic surface. The result, 96120, is obtained using methods from numerical algebraic geometry.
