| Summary:
We study topologically stable defect structures in systems where the defect
line classification in three dimensions and associated algebra of interactions
(the fundamental group) are governed by the non-Abelian 8-element group, the
quaternions Q_8. The non-Abelian character of the defect algebra leads to a
topological rigidity of bound defect pairs, and trivalent junctions which are
the building blocks of multi-junction trivalent networks. We realize such
structures in laboratory chiral nematics and analyze their behavior
analytically, along with numerical modeling.
