Many (22, 44, 14, 7, 4)- and (15, 42, 14, 5, 4)-balanced incomplete block designs
The authors determine the number of non-isomorphic \((22,44,14,7,4)\)-BIBDs whose automorphism group has order divisible by 7 or 11. From this they obtain results on the number of non-isomorphic \((15,42,14,5,4)\)-BIBDs.
