Abstract. Part I reviews the derivation of M-brane charge in equivariant cohomotopy, and explains how bringing in anti-M-branes should enhance this to equivariant stable cohomotopy. Part II presents computations of putative M-brane charge in equivariant stable cohomotopy and comparison to the folklore of perturbative string theory.
