## Abstract A set of trivial necessary conditions for the existence of a large set of __t__βdesigns, __LS__[N](__t,k,__Ξ½), is $N\big | {{\nu \hskip -3.1 \nu}-i \choose k-i}$ for __i__β=β0,β¦,__t__. There are two conjectures due to Hartman and Khosrovshahi which state that the trivial necessary condi
In this paper we give a bound for the cardinality of an intersection set of a 2-(v,k,2) design D. We give a new proof of Drake's inequality for the cardinality of a blocking set of D. Our proof will enable us to characterize the case of equality. We investigate the existence of the blocking sets of
## Abstract Two types of large sets of coverings were introduced by T. Etzion (J Combin Designs, 2(1994), 359β374). What is maximum number (denoted by Ξ»(__n,k__)) of disjoint optimal (__n,k,k__βββ1) coverings? What is the minimum number (denoted by Β΅(__n,k__)) of disjoint optimal (__n,k,k__βββ1) co
