Steiner 3-designs as extensions

Michael Kiermaier, Vedran KrÄadinac, Alfred Wassermann

In this article, we construct a Steiner system with the parameters $S (3, 6, 42)$ , settling one of the smallest open parameter sets of Steiner $3$ -designs. Furthermore, we establish t…

Some new Steiner designs $S (2, 6, 91)$

Michael Kiermaier, Vedran KrÄadinac, Vladimir D. Tonchev +2

The Kramer-Mesner method for constructing designs with a prescribed automorphism group $G$ has proven effective many times. In the special case of Steiner designs, the task reduces…

Projection cubes of symmetric designs

Vedran KrÄadinac, Lucija ReliÄ

We introduce a new type of $n$ -dimensional generalization of symmetric $(v, k, I^»)$ block designs. We prove upper bounds on the dimension $n$ in terms of $v$ and $k$ . We also define…
