The triangular lattice is sometimes called hexagonal lattice, which may cause some confusion. It can be viewed as a skewed rectangular lattice. It surface density is

\rho\sigma^2=\frac{2}{\sqrt{3}},

where \sigma is the distance between nodes of the lattice. The dual of this lattice is the honeycomb lattice.
