Capacity-achieving codes: A review on double transitivity

K Ivanov, RL Urbanke - arXiv preprint arXiv:2010.15453, 2020 - arxiv.org
Recently it was proved that if a linear code is invariant under the action of a doubly transitive
permutation group, it achieves the capacity of erasure channel. Therefore, it is of sufficient …
