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?
