Talk:Schnyder's theorem

Is the Brightwell-Trotter theorem a real generalization of Schnyder's? I mean does Brigtwell-Trotter imply Schnyder? It seems to me that it's statement only implies a weaker version of Shnyder. (Namely that planar graphs have incidence posets of dimension no more that 4.) — Preceding unsigned comment added by 74.141.206.58 (talk • contribs) 10:56, December 17, 2012
