This is strongly related to the concept of residual connectedness in incidence / diagram geometries, and many people used this over the years (me included). | |

| Apr 19, 2011 at 11:25 | comment | added | Jim Humphreys | This occurs on page 5 of the book Buildings of Spherical Type and Finite BN-Pairs, Lect. Notes in Math. 386 (1974), but with simpler notation $X, Y, Z$ for the subgroups which makes for easier typesetting. The three equivalent conditions are called (1), (2), (3). I suspect what Max has written down works. Even though mistakes in mathematics are always possible, the book by Tits has been around for a long time and this "easy" exercise has been looked at by many people. | |
