E8 is a lie group, which is a set of matrices which is closed under inversion and multiplication. In fact, E8 is a very large group. Particle physics is based on a set of smaller groups, but these groups are distinct. A &quot;theory of everything&quot; would embed these smaller groups into a single large group. Lisi showed that you can embed these smaller groups into E8, although he didn&#x27;t show that all the important properties hold. Garibaldi showed that…</p><p><a href="https://hackerpaper.kaipfister.de/p/0905.2658/">Paper and discussion history</a>. A mention is not an endorsement.</p>math.RT
