The bicrossed products of \(H_4\) and \(H_8\). (English) Zbl 07285973
Summary: Let \(H_4\) and \(H_8\) be the Sweedler’s and Kac-Paljutkin Hopf algebras, respectively. We prove that any Hopf algebra which factorizes through \(H_8\) and \(H_4\) (equivalently, any bicrossed product between the Hopf algebras \(H_8\) and \(H_4\)) must be isomorphic to one of the following four Hopf algebras: \(H_8\otimes H_4,H_{32,1},H_{32,2},H_{32,3}\). The set of all matched pairs \((H_8,H_4,\triangleright,\triangleleft)\) is explicitly described, and then the associated bicrossed product is given by generators and relations.
