Table of the orders of the largest known vertex-transitive graphs for the undirected degree diameter problem

Below is the table of the largest known vertex-transitive graphs in the undirected degree diameter problem for graphs of degree 3 ≤ d ≤ 20 and diameter 2 ≤ k ≤ 10. All graphs which are known to be optimal are marked in bold.
