| Mar 18, 2018 at 19:43 | comment | added | Daniele Zuddas | sorry, I misunderstood. So you take a regular simplex in $\Bbb R^n$ all of whose vertices belong to $S^n$, isn't? | |
| Mar 18, 2018 at 19:36 | comment | added | Dmitri Panov | THE regular simplex in $S^n$ has $n+2$ vertices. The example that I propose is just the generalization of yours | |
| Mar 18, 2018 at 19:35 | comment | added | Daniele Zuddas | but a simplex in $\Bbb RP^n$ has at most $n+1$ vertices, depending on its dimension | |
| Mar 18, 2018 at 19:33 | comment | added | Dmitri Panov | Because this is so for $S^n$ | |
