There are only finitely many distance-regular graphs with valency k at least three, fixed ratio k2/k and large diameter
Jongyook Park, Jack H. Koolen, Greg Markowsky
In this paper, we show that for given positive integer C, there are only finitely many distance-regular graphs with valency k at least three, diameter D at least six and k2/k<=C. T…

A conjecture of Biggs concerning the resistance of a distance-regular graph
Greg Markowsky, Jacobus Koolen
Previously, Biggs has conjectured that the resistance between any two points on a distance-regular graph of valency greater than 2 is bounded by twice the resistance between adjace…
