On the classification of 2-generated axial algebras of Majorana type

A class of axial algebras generated by two axes with eigenvalues 0, 1, η and ξ called Majorana type is introduced classified when they are 2-generated, over fields characteristics neither 2 nor 5 there exists an automorphism switching generating axes. The includes deformations nine Norton-Sakuma algebras. Over 5, the dimension at most classified.
