    abstract     = {The author gives a description of oriented 3-manifolds (including singular ones in the sense of {\it J. M. Montesinos} [Math. Proc. Camb. Philos. Soc. 94, 109-123 (1983; Zbl 0535.57007)] by a family of 4-coloured graphs, generalizing work of Lins, Mandel and Cavicchioli. The manifolds are finite coverings of $S^3$ bounded along a knottet $\theta$-graph or handcuff-graph resp. a 2-bridge knot or link. This includes Montesinos' universal graph. A necessary and sufficient condition for the covering space to be a manifold is given in terms of the data of the graph.},
