testgraph=Graph[#[[1]]\[DirectedEdge]#[[2]]&/@{{1,3},{2,3},{3,4},{3,5},{4,6},{4,7},{5,7},{6,7}}, VertexLabels->"Name", ImagePadding->10] MatrixForm[AdjacencyMatrix[testgraph], TableHeadings -> {Range[7], Range[7]}] The Adjacency Matrix appears to be incorrect, e.g. 1 is not adjacent to 2. What am I missing?
