A connected graph G is distance-regular if for any vertices x and y of G and any integers i,j=0, 1, ...d (where d is the graph diameter), the number of vertices at distance i from x and distance j from y depends only on i, j, and the graph distance between x and y, independently of the choice of x and y. In particular, a distance-regular graph is a graph for which there exist integers b_i,c_i,i=0,...,d such that for any two vertices x,y in G and distance i=d(x,y), there are exactly c_i...

As someone who is passionate about both mathematics and programming languages, I thought I would share what I consider to be 10 great programming languages for mathematics. I aimed for variety in doing so, to give you a broad spectrum of approaches to programming and problem modeling. The language descriptions are straight from their respective sites or wikipedia pages, but I’ve added my two cents throughout the list as well. 1. Wolfram Language The Wolfram Language is the programming language of Mathematica and of the Wolfram Programming Cloud. It is a general multi-paradigm programming language developed by Wolfram Research. It
