$3$-generated axial algebras with a minimal Miyamoto group

TL;DR

This paper classifies nearly all 3-generated axial algebras with minimal Miyamoto groups, extending previous work by computing more algebras without assuming primitivity or an associating bilinear form.

Contribution

It computes a broad class of 3-generated axial algebras with minimal Miyamoto groups, expanding the classification beyond prior assumptions.

Findings

Almost all 3-generated axial algebras with minimal Miyamoto group identified

Extended previous classifications by including non-primitive cases

Provided new examples of axial algebras beyond existing classifications

Abstract

Axial algebras are a recently introduced class of non-associative algebra, with a naturally associated group, which generalise the Griess algebra and some key features of the moonshine VOA. Sakuma's Theorem classifies the eight $2$-generated axial algebras of Monster type. In this paper, we compute almost all the $3$-generated axial algebras whose associated Miyamoto group is minimal $3$-generated (this includes the minimal $3$-generated algebras). We note that this work was carried out independently to that of Mamontov, Staroletov and Whybrow and extends their result by computing more algebras and not assuming primitivity, or an associating bilinear form.
