Theory predicts that the defects in liquid crystals of biaxial nematic type have some unusual properties : disclination lines would combine like quaternions, i.e. in a non commutative way. This leads to a topological rigidity which merits an experimental study.Les prédictions théoriques pour les défauts des cristaux liquides du type nématique biaxe suggèrent des propriétés inusuelles : des lignes de disclination qui se combinent comme des quaternions, c'est-à-dire de manière non commutative. Il s'ensuit une rigidité topologique qui mérite une étude expérimentale
