Construction of s-extremal optimal unimodular lattices in dimension 52

Research output: Contribution to journalArticlepeer-review


An s-extremal optimal unimodular lattice in dimension 52 is constructed for the first time. This lattice is constructed from a certain self-dual (Formula presented.) -code by Construction A. In addition, as neighbours of the lattice, two more s-extremal optimal unimodular lattices are constructed.
