If x- (i = 1, 2, ... , 6) are homogeneous co-ordinates in [5] (the complex projective space of five dimensions), then the equation 1.1 represents the well-known (11) Perazzo cubic primalP43 of order 3 and dimension 4. With it is associated the Segre cubic threefoldS33 (12); specifically, S33 is the section of P4 3 by a tangent [4].
