08/19/200459Final sentence should read: "Such a relationship is called involutory."
29/11/2004104Definition of closure should read: "Let S be a topological space and X be a subset of points of S. Then the closure of X is the union of X with the set of all its near points."
02/12/2004113The definition of strongly connected should read: "A set X in the Euclidean plane with the usual topology is strongly connected if it is connected and not weakly connected."
01/06/2006115Fourth sentence of final paragraph should read: "This is rectified by ... decomposing the original simplexes abc and def ..."
29/11/2004117 & 118On p118, the direction of the arrows on Figure 3.39 should be reversed for directed arcs 3 and 4. As a result, the corresponding sentence on p117 should read: "Thus we have found two cycles [1,2] and [4,3]."
17/01/2010121An edge connecting the two middle nodes is missing from Figure 3.44b. This edge must be added for the graph to be non-planar---specifically the graph K(3,3).

12/15/2006237Figure 6.13. Labels SE and SW should be swapped for one another. Left to right the labels should read: NW, NE, SW, SE.
06/18/2006248Figure 6.24. Node 3 should additionally have node 14 as its second descendant.
01/06/2006253Figure 6.29. The left-hand edge of rectangle P should overlap the left-hand edges of rectangles T and W
