| Mar 1, 2018 at 19:49 | comment | added | darij grinberg | $\operatorname{Sym}^7 \left(\wedge^3 \mathbb{C}^6\right)$ has the representation corresponding to partition $\left(5, 5, 5, 2, 2, 2\right)$ appearing twice. Thus, not very multiplicity-free. | |

| Mar 1, 2018 at 18:07 | comment | added | Abdelmalek Abdesselam | You are basically asking about the full list of invariants and mixed concomitants of an alternating 3-form in 6 variables. I would try to look at the book by Gurevich on invariant theory as well as the more classical book by Turnbull. Also Rota and his school studied invariants of antisymmetric tensors using so called letter-place algebras. | |
