A bstractWe study generalized diffeomorphisms in exceptional geometry with U-duality group En(n) from an algebraic point of view. By extending the Lie algebra en$$ {\mathfrak{e}}_n $$ to an infinite-dimensional Borcherds superalgebra, involving also the extension to en+1$$ {\mathfrak{e}}_{n+1} $$, the generalized Lie derivatives can be expressed in a simple way, and the expressions take the same form for any n ≤ 7. The closure of the transformations then follows from the Jacobi identity and the grading of en+1$$ {\mathfrak{e}}_{n+1} $$ with respect to en$$ {\mathfrak{e}}_n $$.
