| Mar 6 at 15:58 | comment | added | macbeth | Thanks! I'll have to study this -- at first glance it's an explicit version for a different version of the Cheeger finiteness theorem than the one I asked about, but maybe there's a way of using it to answer my question. | |

| Feb 7 at 2:12 | comment | added | macbeth | By Brendle-Schoen, $\delta<\tfrac{1}{4}$ if it's not a sphere and not a symmetric space. So any of the other examples listed in section 2 of this survey of Ziller should have $\delta<\tfrac{1}{4}$. (And some of those are even-dimensional.) | |
