| Apr 4, 2019 at 8:09 | comment | added | FKranhold | Thank you! Am I correct that the Cayley graph (i) is an $\mathfrak{S}_3$-covering of $\mathbb{S}^1\vee\mathbb{S}^1$ as suggested by Gustavo and $\mathfrak{S}_3$ acts as follows: $x$ rotates the triangle by $120^\circ$ and $y$ inverts inner and outer and reflects once? And is it correct that adding the three $2$-cells (resp. eighteen $2$-cells above) gives another $\mathfrak{S}_3$-covering which is the universal covering of the base? And that we have two $2$-cells per bigon and $4$-gon and three for each of the two triangles? | |
