New sequences of non-free rational points
Comptes Rendus. Mathématique, Tome 359 (2021) no. 8, pp. 983-989.

We exhibit some new infinite families of rational values of τ, some of them squares of rationals, for which the group or even the semigroup generated by the matrices (1101) and  (10τ1) is not free.
