Neither $\prod_{k = 1}^{n} (4 k 2 + 1)$ nor $\prod_{k = 1}^{n} (2 k (k - 1) + 1)$ is a perfect square.

Nombres de racines d’un polynôme entier modulo $q$

Monique Branton, Olivier Ramaré (1998)

Journal de théorie des nombres de Bordeaux

Nous montrons que l’ensemble des racines modulo une puissance d’un nombre premier d’un polynôme à coefficients entiers de degré $d$ est une union d’au plus $d$ progressions arithmétiques de modules assez grands. Nous en déduisons une majoration du nombre de ses racines dans un intervalle réel court.
