The complete 3-uniform hypergraph of order v, denoted by K-v((3)), has a set V of size v as its vertex set and the set of all 3-element subsets of V as its edge set. A 3-uniform tight 9-cycle has vertex set {v(1), v(2), v(3), v(4), v(5), v(6), v(7), v(8), v(9)} and edge set { {v(1), v(2), v(3)}, {v(2), v(3), v(4)}, {v(3), v(4), v(5)}, {v(4), v(5), v(6)}, {v(5), v(6), v(7)}, {v(6), v(7), v(8)}, {v(7), v(8), v(9)}, {v(8), v(9), v(1)}, {v(9), v(1), v(2)}}. We show there exists a tight 9-cycle decomposition of K-v((3)) if and only if v equivalent to 1 or 2 (mod 27).
