"WebMiller-Bravais indices are a 4-axis coordinate system for 3-dimensional crystals, based on the unit cell. This coordinate system is based on the 3-axis Miller index, but with an extra axis which is used for hexagonal crystals. The system can indicate directions or planes, and are often written as (hkil).
