Simple 8-(40,11,1440) designs Original Research Article

In this short note, simple 8-(40,11,1440) designs with automorphism group PSL(4,3) are presented. The designs are constructed with the method of Kramer and Mesner on a computer using the software package DISCRETA (Betten et al., A tool for constructing t-designs, Lehrstuhl II für Mathematik, Universität Bayreuth. Software package and documentation available under http://www.mathe2.uni-bayreuth.de/betten/DISCRETA/Index.html).
