We consider the Z2 topology of the Dirac lines, i.e., lines of band contacts, on an example of graphite.
Four lines—three with topological charge N1 = 1each and one with N1 = -1—merge together near
the H-point and annihilate due to summation law1 ++-= 1110. The merging point is similar
to the real-space nexus, an analog of the Dirac monopole at which the Z2 strings terminate.
