thanks, hadn’t seen that (and it seems unpublished?) BTW, we do have an entry for Yang-Hui He

1. Added connection and reference between the Leech lattice and the octonions.

He ends with applications:

• Perhaps this gives us a better understanding of why the Leech lattice exists.

• Perhaps it will give us new ways to prove important properties of the Leech lattice and the Conway group.

• Perhaps we can use octonions to simplify the construction of the Monster.

• Perhaps it will explain the ‘2-local group’ BDI(4) which contains Co3 and looks as though it should be some kind of twist of ‘skew-symmetric 3×3 matrices over octonions’

Could one dare to hope that growing the superpoint $\mathbb{R}^{0|3}$ could make contact with these things?
