Some characterizations of the exceptional planar embedding of W(2)
In this paper, we study the representation of W(2) in PG(2, 4) related to a hyperoval. We provide a group-theoretic characterization and some geometric ones.

Improving diameter bounds for distance-regular graphs
In this paper we study the sequence (ci)0id for a distance-regular graph. In particular we show that if d 2j and cj = c > 1 then c2j > c holds. Using this we give improveme...
