We give precise formulas of the 3-Lie algebra $((A\oplus A^*)^*, \Delta^*)$ and show that the local cocycle 3-Lie bialgebra $(A\ltimes_{\ad^*} A^*, \Delta)$ induced by the involutive derivation $D$ gives rise to a Manin triple of 3-Lie algebras. We give examples of $12$-dimensional and $16$-dimensional Manin triples using involutive derivations on certain $3$-dimensional and $4$-dimensional $3$-Lie algebras. Keywords: 3-Lie algebra, involutive derivation, semi-direct product 3-Lie algebra, Manin triple, 3-Lie bialgebra. MSC: 16T10, 16T25, 17A30, 17B62. [ Fulltext-pdf  (162  KB)] for subscribers only.
