Switching networks of the type used in telephone exchanges are studied, with emphasis on a particular class of networks possessing great structural symmetry. This class contains rearrangeable networks carrying N calls with roughly 6N log3 N contacts, and non-blocking networks with roughly 16N(log5 N)2 contacts; these results are the best obtainable by the methods used. We also show, by an impractical argument, that there are non-blocking networks with roughly 90N log3 N contacts. © 1978.
