Abstract
We complete the proof of the fact that every locally finite triangle building Δ with a half strongly-transitive automorphism group G (e.g., this happens when Δ is defined via a (B, N)-pair in G) is a Bruhat—Tits building associated with a classical linear group over a locally finite local skewfield.
