A description of the outer automorphism of \(S_6\), and the invariants of six points in projective space

• Published in 2008
• Added on 2018-05-14

We use a simple description of the outer automorphism of \(S_6\) to cleanly describe the invariant theory of six points in \(\mathbb{P}^1\), \(\mathbb{P}^2\), and \(\mathbb{P}^3\).

Comment

The nobbly wobbly toy is based on this.
