A generalized strongly regular graph of grade p, as a generalization of strongly regular graphs, is a regular graph such that the number of common neighbours of both any two adjacent vertices and any two non-adjacent vertices takes on p distinct valu

Let Meta(H > T, ?) denote the set of all integers v such that there exists a (H > T)-GM ? (v). In this paper, the set Meta(H > T, ?) will be completely determined for the following 21 pairs (H, T) = (H 1, P 2), (H 2, 2P 2), (H 3, P 3) and (H 4, P 4),

The determination of the existence of large sets of Kirkman triple systems (LKTS) is a classical combinatorial problem. In this paper we introduce a new concept OLGKS—overlarge sets of generalized Kirkman triple systems and show the relationship be

An overlarge set of KTS(v), denoted by OLKTS(v), is a collection {([email protected]?{x},B"x):[email protected]?X}, where X is a (v+1)-set, each ([email protected]?{x},B"x) is a KTS(v) and {B"x:[email protected]?X} forms a partition of all triples on

A large set of Kirkman triple systems of order v, denoted by LKTS(v), is a collection $$\{(X, \mathcal {B}_i) : 1 \leq i \leq v - 2\}$$ , where every $$(X, \mathcal {B}_i)$$ is a KTS(v) and all $$\mathcal {B}_i$$ form a partition of all triples on X.

A large set of Kirkman triple systems of order v, denoted by LKTS(v), is a collection {(X, Bi) : 1 ≤ i ≤ v − 2}, where every (X,Bi) is a KTS(v) and all Bi form a partition of all triples on X. Many researchers have studied the existence of LKTS
