  Recent reports of room temperature ambient pressure superconductivity in
LK-99 sparked tremendous excitement. While the materials is no longer believed
to be superconducting, interest in its electronic and topological properties
still stands. Here, we utilize first-principle density functional theory and
augment a recently proposed model tight-binding Hamiltonian to study the band
topology including the impact of spin-orbit coupling. In the absence of
spin-orbit coupling, we observed the presence of two isolated bands situated
near the Fermi level. However, upon the introduction of spin-orbit coupling,
these two bands split into four bands and generate multiple Weyl points with
Chern number $\pm 2$. We also find accidental crossings along high symmetry
lines which, at the level of our minimal Hamiltonian, extend as nodal surfaces
away from these lines.
