The three levels are:{1,2,3},{4,5,6},{7,8,9} They give triangular states as: {1} :as 0th state {4, 5, 4}, {8, 9, 8}, {2, 3, 2, 3, 1, 3, 2, 3, 2}, {5, 6, 5, 6, 4, 6, 5, 6, 5, 6, 4, 6, 4, 5, 4, 6, 4, 6, 5, 6, 5, 6, 4, 6, 5, 6,5}, {9, 7, 8, 9, 9, 7, 8, 9, 8, 7, 8, 9, 9, 7, 8, 9, 9, 7, 8, 9, 8, 7, 8, 9, 8, 9, 8, 7, 8, 9, 8, 7, 8, 9, 9, 7, 8, 9, 9, 7, 8, 9, 8, 7, 8, 9, 9, 7, 8, 9, 9},
