Abstract: We study the class of idempotent-generated pseudo-composition algebras, which is a subclass of the family of axial algebras. More specifically, we utilise the group-algebra correspondence, natural to the axial framework in order to study some automorphism subgroups of such pseudo-composition algebras.

Keywords: pseudo-composition algebra, axial algebra, Miyamoto involution, automorphism group.
