- p 322, the proof that an incidence relation is symmetric as
written assumes the conclusion x \subset y. Instead, assuming mx
\subset y \subset x, let y'=m^{-1}y, from which it follows that x
\subset y, from whence the desired assertion.
- pp 336-337 defining an incidence relation to give the affine
building for \tilde C_n. The defining relation should be
\Lambda_0 \subset y \subset m^{-1}\Lambda_0. As written, the leftmost
\Lambda_0 had a spurious factor of m in front of it.
