Abstract

In this paper we solve the Diophantine equation (ml)(nk)=d\binom{m}{l}-\binom{n}{k}=d (where m,n are positive integers unknowns) when (k,l)=(3,6) for various values of d and when (k,l)=(8,2) and d=1. As a byproduct of our results we will obtain that (k,l)-near collisions with difference 1 do not exist if (k,l)=(6,3), (3,6), (8,2) thus establishing a conjecture stated in the article "Binomial collisions and near collisions" published by A. Blokhuis, A. Brouwer and B. de Weger in Integers 17 (2017), A64.
