Generate the directed graph gr = Graph[Join @@ (Thread[DirectedEdge @@ #1] & ) /@ {{1, {11, 6, 13, 22}}, {2, {35, 10, 12, 8, 28}}, {3, {23, 31, 19, 14, 11}}, {4, {9, 15, 7, 13, 33, 19}}, {5, {28, 8, 32, 34}}, {6, {27, 13, 1, 11, 20}}, {7, {13, 4, 15, 17, 21, 32, 8}}, {8, {7, 32, 5, 28, 2, 12}}}] then evaluate AdjacencyMatrix[gr] or Normal@AdjacencyMatrix[gr].
