For each positive even integer n, let Fn(a,b,c,d)=(a+b+c)n+(b+c+d)n−(c+d+a)n−(d+a+b)n+(a−d)n−(b−c)n. The remarkable identity referred to in the title is the following: If a,b,c and d are numbers satisfying ad=bc then 64F6(a,b,c,d)F10(a,b,c,d)=45F28(a,b,c,d).(1) Ramanujan, as was his custom, gave no proof. The authors first verified that (1) is true with the aid of the symbolic algebra system Mathematica. However, as they point out, such a proof is less than satisfactory, since it gives no information as to how (1) might have been discovered. In the paper they give an elementary proof of (1) which gives some insight as to why it exists.
