ScholarBank@NUS Repository. | Abstract: | A t-(v, k, λ) covering is an incidence structure with v points, each block incident on exactly k points, such that every set of t distinct points is incident on at least λ blocks. By considering certain geometries over finite principal ideal rings, we construct infinite families of t-(v, k, λ) coverings having many interesting combinatorial properties. © 1999 John Wiley & Sons, Inc. | Source Title: | Journal of Combinatorial Designs | URI: | http://scholarbank.nus.edu.sg/handle/10635/102998 | ISSN: | 10638539 |
