A generalization of the notion of tangent bundle in exceptional generalized geometry.
For 11-dimensional supergravity the bosonic body of its typical fiber is
where the second summand corresponds to M2-brane charges and the third to M5-brane charges.
This happens to coincide with the bosonic body of the M-theory super Lie algebra, see there for more.
