| Dec 20, 2014 at 16:58 | comment | added | David E Speyer | In the positive direction, I recently encountered a result of Hoehnke and Johnson, arxiv.org/abs/math/9210219 : A group is determined by the collection of functions $G^k \to \mathbb{C}$ for $k=1$, $2$ and $3$ given by $g \mapsto \chi(g)$, $(g,h) \mapsto \chi(g)\chi(h)- \chi(gh)$ and $(f,g,h) \mapsto \chi(f) \chi(g) \chi(h) - \chi(fg) \chi(h) - \chi(gh) \chi(f) - \chi(h) \chi(fg) + \chi(fgh) + \chi(fhg)$ for all characters $\chi$. | |
