Abstract
The direct product (also called Kronecker product, tensor product, and card inal product) G x H of distance-regular graphs is investigated. It is demon strated that the product is distance-regular only when G and H are very res tricted distance-regular graphs. (C) 1999 Elsevier Science Ltd. All rights reserved.
