We can recover \(M\) from a Heegaard diagram; more generally, given a cube with \(n\)-handles, \(V_1\), and a collection \(\{J_1,\ldots,J_n\}\) of pairwise disjoint, 2-sided 1-spheres in \(\partial V_1\) which cut \(\partial V_1\) into a 2-sphere with \(2n\) holes, then \((V_1;J_1,\ldots,J_n)\) is a Heegaard diagram associated with a Heegaard Splitting of a uniquely determined closed 3-manifold \(M\).
