Title: Equations for the Fifth Secant Variety of Segre Products of Projective Spaces

Abstract:  We describe a computational proof that the fifth secant variety of the Segre product of five copies of the projective line is a codimension 2 complete intersection of equations of degree 6 and 16. Our computations rely on pseudo-randomness, and nu- merical accuracy, so parts of our proof are only valid ``with high probability.'' This is joint work with Steven Sam (UC Berkeley).
