Description
The 4-dimensional hypercubic lattice has a symmetry group with 384 elements. The 16-cell honeycomb lattice has 3 times as many elements, hence a larger symmetry. Motivated by this fact we discretize lattice QCD on this lattice and observe better scaling for gauge observables and better chiral properties for the Wilson-type Dirac operator. Even though a lattice site has 24 neighbors and not 8 as with the hypercubic lattice, the over-all cost gain in dynamical simulations is expected to be significant due to the better scaling properties.
