Dear VASP developers/uders,
When tetrahedron method is used, 'tetrahedron connection table' is written in IBZKPT file. Would anyone explain the meaning of this 'tetrahedron connection table'?
Thank you.

IBZKPT file
it is the list of tetrahedra build with your k-point set.
first number is the weight, second to fifth are the 4 vertices of each tetrahedron.
Keep in mind that the indices are for irreducible K-points,
So for a kpointfile:
2x2x2 Momkhorstpack, with IRBZKPT 1: 0.5 0.5 0.5
you will probably see 6 1 1 1 1 which tells you that a cube can be split in 6 tetrahedra ;-)
