A non-existence result and large sets for Sarvate-Beam designs
نویسندگان
چکیده
It is shown that for 2 ≤ t ≤ n− 3, a strict t-SB(n, n− 1) design does not exist, but for n ≥ 3, a non-strict 2-SB(n, n−1) design exists. The concept of large sets for Steiner triple systems is extended to SB designs and examples of a large sets for SB designs are given.

Beautifully Ordered Balanced Incomplete Block Designs
Beautifully Ordered Balanced Incomplete Block Designs, BOBIBD(v, k, λ, k1, λ1), are defined and the proof is given to show that necessary conditions are sufficient for the existence of BOBIBD with block size k=3 and k1=2 and for k=4 and k1=2 except possibly for eleven exceptions. Existence of BOBIBDs with block size k=4 and k1=3 is demonstrated for all but one infinite family and the non-existe...
متن کاملA complete existence theory for Sarvate-Beam triple systems
An ordinary block design has v points, blocks of size k, and each of the ( v 2 ) unordered pairs of points is contained in a common number λ of blocks. In 2007, Sarvate and Beam introduced a variation where rather than covering all pairs a constant number of times, one wishes to cover all pairs a different number of times. It is of greatest interest when these pair frequencies form an interval ...
متن کاملSarvate – Beam Triple Systems
A Sarvate–Beam Triple System SB(v, 3) is a set V of v elements and a collection of 3–subsets of V such that each distinct pair of elements in V occurs in i blocks, for every i in the list 1, 2, . . . , ( v 2 ) . In this paper, we completely enumerate all Sarvate-Beam Triple Systems for v = 5 and v = 6. (In the case v = 5, we extend a previous result of R. Stanton [8].) 1 Sarvate–Beam Designs Th...
متن کاملBalanced part ternary designs: some new results
A balanced part ternary design (BPTD) is a balanced ternary design (BTD) with a specified number of blocks, say b2, each having repeated elements. We prove some necessary conditions on b2 and show the existence of some particular BPTDs. We also give constructions of infinite families of BPTDs with b1 = 0, including families of ternary t-designs with t ≥ 3.
متن کاملA Family of Group Divisible Designs of Block Size Four and Three Groups With l1=2 and l2=1 Using MOLS
We give a construction for a new family of Group Divisible Designs (6s+ 2, 3, 4; 1, 2) using Mutually Orthogonal Latin Squares for all positive integers s. Consequently, we have proved that the necessary conditions are sufficient for the existence of GDD’s of block size four with three groups, λ1=2 and λ2=1.
