Abstract

In this work, a universal branching set K for orientable 4-manifolds, such that $\pi_1(S^4 - K) = [a, b, c/aca^{-1}c^{-1} =1]$ is proved to exist. This leads to the possibility of representing every closed connected orientable 4-manifold by a suitable transitive set $\{\sigma, \tau, \mu\}$ of permutations, in analogy with known results for dimension three (see [Montesinos] and [Costa-delValMelus]).
