Abstract
In 1954 H. S. Shapiro proposed an inequality for a cyclic sum in n variables.
All the numerical evidence indicates that the inequality is true for even n≤12
and for odd n≤23. We give an analytic proof for the case n=12, which implies
the former result. The remaining case n=23 remains an open problem.
