Sažetak

By using a method of construction of block-primitive and point-transitive 1-designs, in this paper we determine all block-primitive and point-transitive 1-\((v, k, \lambda)\)-designs from the maximal subgroups and the conjugacy classes of elements of the small Mathieu group \({\rm M}_{11}\). We examine the properties of the 1-\((v, k, \lambda)\)-designs and construct the codes defined by the binary row span of their incidence matrices. Furthermore, we present a number of interesting \(\Delta\)-divisible binary codes invariant under \({\rm M}_{11}\).
