It has close relations to coding theory, lattice theory, number theory, modular forms. John Conway [1] (who recently passed away due to COVID) wrote a famous book about it: Sphere Packings, Lattices and Groups -- which summarizes the subject concisely. A recent (2017) break through, was the proof that the Leech Lattice [2] yields the optimal sphere packing in dimension 24 [3]. The error correcting code constructed from this lattice is the Binary Golay Error Correcting Code [4]. It is able to correct 3 bits for every 24…</p><p><a href="https://hackerpaper.kaipfister.de/p/1603.06518/">Paper and discussion history</a>. A mention is not an endorsement.</p>math.NT
