Some designs and codes invariant under the Tits group. (English) Zbl 1357.05019

Summary: In this paper, we construct some designs and associated binary codes from a primitive permutation representation of degree 1755 of the sporadic simple Tits group \({}^2F_4(2)'\). In particular, we construct a binary code \([1755, 26,1024]_2\) on which \({}^2F_4(2)'\) acts irreducibly. This is the smallest non-trivial irreducible \(\mathrm{GF}(2)\)-module for our group.
