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].
