vertices

This was practically confirmed using a vertex cover problem with 4096 vertices.

The hexagonal symmetry observed in this so-called real space is also present in momentum space, where the vertices of the lattice don't correspond to the spatial locations of carbon atoms but to values of momentum associated with the free electrons on the lattice.

While place cells fire whenever an animal is in a specific location, grid cells fire only when the animal is at one of the vertices of a triangular lattice.

Deneb is apparently the faintest of the stellar triangle vertices, but don’t be fooled.

In the Blue Brain graph, for example, three neurons with all three synapses between them transmitting signals formed the vertices of a hollow triangle.
