added to supergravity Lie 3-algebra the proposition that the automorphism $\infty$-Lie algebra of $\mathfrak{sugra}(10,1)$ is in degree 0 the quasi-central extension of the super Poincaré Lie algebra (the one that is also known as the “M-theory Lie algebra”).

This result is due to the article by Leonardo Castellani which I cite there. Only that he does not quite say it that way. (I think what he says about what he is doing does not quite make sense. But what he actually does is good. He computes the automorphism infinity-Lie algebra). All mention of “soft group manifolds” can and – I think – should be ignored.

bit rough, but have to go offline now, am on the plane, take-off in a few minutes…
