It has been known for some time that an Ss(3, 4, v) exists iff v is even. The constructions which prove this result, in general, give designs having repeated blocks. Recently, it was shown that a simple Ss(3, 4, v) exists if v is even and v 3.4 (mod 12). In this paper we give an elementary proof of

## Abstract A word of length __k__ over an alphabet __Q__ of size __v__ is a vector of length __k__ with coordinates taken from __Q__. Let __Q__^\*^~4~ be the set of all words of length 4 over __Q__. A __T__^\*^(3, 4, __v__)‐code over __Q__ is a subset __C__^\*^βŠ† __Q__^\*^~4~ such that every word o

In this article, we investigate the existence of pure (v,4,A)-PMD with A = 1 and 2, and obtain the following results: (1) a pure (v, 4,1)-PMD exists for every positive integer Y = 0 or 1 (mod 4) with the exception of v = 4 and 8 and the possible exception of v = 12; (2) a pure (v,4,2)-PMD exists for

It is well known that a triplewhist tournament TWh(v) exists only if v ≑ 0 or 1 (mod 4) and v = 5, 9. In this article, we introduce a new concept TWh-frame and use it to show that the necessary condition for the existence of a TWh(v) is also sufficient with a handful possible exceptions of v ∈ {12,
