I need a sorting algorithm to sort 5 items using only 7 comparisons. I remember seeing a similar problem somewhere in my undergraduate days, but cannot find it in my notes.

Similar formulas exist for finding the roots of a quartic equation. Derivations are similar and may be found in some handbooks of math tables and formulas. It is well-known that such formulas cannot be found for quintic or higher degree polynomials in general.
