Chapter 3, Problem 3.56P
Interpretation Introduction

Interpretation:

The indices for the directions in the hexagonal lattice using three-digit and four-digit systems are to be determined.

Concept Introduction:

The indices for the hexagonal structure needs to be written at given direction A, B, C. For hexagonal lattice, the three-digit system uses three indices (h,k,l) and the four-digit system uses four indices (h,k,i,l)
