| Nov 22, 2012 at 2:25 | comment | added | Robert Bryant | @Sergei: That's a nice example. It, too, has a lot of symmetry since it is invariant under the diagonal action of $\mathrm{O}(3)$ when you split it as $(x_1,x_3,x_5)\oplus(x_2,x_4,x_6)$. That plus the obvious scaling and exchange makes a group of dimension $4$ that acts irreducibly on $\mathbb{R}^6$. Is there a larger subgroup of $\mathrm{GL}(6)$ that preserves this subspace of $\Lambda^2(\mathbb{R}^6)$? | |
