    A theorem on the 3-connectivity of matroids is given, which has many new and old connectivity results as corollaries. E.g. if M' is a 3-connected proper minor on at least four elements of a 3-connected matroid M then M has a 3-connected minor M'' which has M' as a proper minor and has at most 3 additional elements beyond those of M'.
