Abstract
We define certain algebras ℭ(n) over a commutative ring K based on the combinatorics of n dots. If K is a field of characteristic 2, then ℭ(n) decomposes as G(n) ⊗𝔽2K where G(n) belongs the infinite sequence of simple Lie algebras over the field 𝔽2 that was introduced by Kaplansky in 1982. We show that Aut(ℭ(n)) is isomorphic to {±1} × 𝔖n for n > 4.
