Segre cubic
In algebraic geometry, the Segre cubic is a cubic threefold embedded in 4 dimensional projective space, studied by .The Segre cubic is the set of points of P5 satisfying the equations\displaystyle x_0+x_1+x_2+x_3+x_4+x_5= 0\displaystyle x_0^3+x_1^3+x_2^3+x_3^3+x_4^3+x_5^3 = 0.Its intersection...
