WebA quadratic has only 2 roots, and only 2!=2 permutations. A cubic has 3 roots, so 3!=6 permutations. For the cubic, we manage to exploit some symmetries of the problem to reduce it to a quadratic equation. The quartic has 4 roots, and 4!=24 permutations, but we still manage to reduce it to a cubic equation by exploiting more symmetries.
