Given a finite collection L of lines in the hyperbolic plane H, we denote by k = k(L) its Karzanov number, i.e., the maximal number of pairwise intersecting lines in L, and by C(L) and n = n(L) the set and the number, respectively, of those points at infinity that are incident with at least one line
For two different integral forms K of the exceptional Jordan algebra we show that Aut K is generated by octave reflections. These provide ''geometric'' examples Ž . of discrete reflection groups acting with finite covolume on the octave or Cayley 2 Ž hyperbolic plane ޏH , the exceptional rank one
