The limit for coverings is v<100, k<=25, and t<=8 just to draw the line somewhere. Only coverings with at most 100000 blocks are given, except for some which were grandfathered in. Some Steiner systems (coverings in which every t-set is covered exactly once) which are too big for the database will be included in the link below.
