ABSTRACT
We find exact solutions to the field equations of eleven-dimensional supergravity corresponding to stable multi-membrane configurations. Their holonomy group is given by the SO(8) subgroup of an enlarged tangent space group SO(1, 2) × SO(16), and hence one half of the spacetime supersymmetries are broken. The solutions saturate a Bogomol’nyi bound between the mass per unit area and the Page charge, which also guarantees their stability.
