Extremal Lattices in $\operatorname{II}_{20}(5^{+10})$
Two new twenty-dimensional five-modular lattices have been found; finally settling the question of the existence of such lattices.

TwoNeighbours is an ongoing project to bring the Two Neighbours of B. Hemkemeier (TN) and the Hermitian Neighbours of A. Schiemann (HN) back to life. Written in modern C++, using parallel algorithm whenever possible and with CUDA support, TwoNeighbours is an algebra system with a focus on algorithms for integral lattices.
