Geometric properties are used to determine the chromatic number of AG(4, 3) and to derive some important facts on the chromatic number of PG(n, 2). It is also shown that a 4-chromatic STS(v) exists for every admissible order v β₯ 21.

## Abstract A __Steiner quadruple system__ of order __v__ (briefly SQS (__v__)) is a pair (__X__, $\cal B$), where __X__ is a __v__βelement set and $\cal B$ is a set of 4βelement subsets of __X__ (called __blocks__ or __quadruples__), such that each 3βelement subset of __X__ is contained in a uniqu
The concept of star chromatic number of a graph, introduced by Vince ( ) is a natural generalization of the chromatic number of a graph. This concept was studied from a pure combinatorial point of view by . In this paper we introduce strong and weak star chromatic numbers of uniform hypergraphs and
## Abstract We show that, up to an automorphism, there is a unique independent set in PG(5,2) that meets every hyperplane in 4 points or more. Using this result, we show that PG(5,2) is a 5βchromatic STS. Moreover, we construct a 5βchromatic STS(__v__) for every admissible __v__ β₯ 127. Β© 1994 John
