| Feb 15, 2015 at 12:26 | comment | added | Sebastien Palcoux | @JohnShareshian: Thank you, I will fix the picture. Michael Aschbacher attributes this conjecture to you in his paper above p72. Do you prefer I call it Aschbacher-Shareshian's conjecture? | |

I've fixed the conjecture and the picture

| Feb 15, 2015 at 2:39 | comment | added | John Shareshian | One more small correction. I believe that the conjecture you attribute to me is a special case of two more general conjectures, one due to Michael Aschbacher and the other due to me. | |
| Feb 15, 2015 at 2:31 | comment | added | John Shareshian | This picture is not quite right. The top and bottom elements from each Boolean algebra should be removed. (That is, the two coatoms and the two atoms in the picture should not be there.) To be clear, I do not know whether the pictured lattice is isomorphic with an interval in the subgroup lattice of a finite group. | |
