## Abstract In this article, we introduce a new orderly backtrack algorithm with efficient isomorph rejection for classification of __t__βdesigns. As an application, we classify all simple 2β(13,3,2) designs with nontrivial automorphism groups. The total number of such designs amounts to 1,897,386.
## Abstract In this paper, we introduce some intersection matrices for __t__βdesigns. Utilizing these matrices together with a modified version of a backtracking algorithm, we classify all 6β(14,7,4) and 5β(13,6,4) designs with nontrivial automorphism groups and obtain 13 and 21 such designs, respe
