and finally multiply by a common (factor) denomenator. Which is 6, to obtain the miller indices (3 4 6). Exercise: x = 2a, y = 3b, z = 6c (321). The indices of some important planes in a cubic crystal

Let the plane have intercepts 4, 1 and 2 on the three axes. The reciprocals are ¼ , 1 and ½. Multiplying each by 4, we get 1, 4 and 2. Hence (142) are the Miller Indices of the plane. Orientation of a crystal plane in a lattice is specified by Miller Indices. These are denoted as h,k & l (the plane is denoted as (hkl) ). These are defined as the reciprocal of the intercepts by the plane on the axes.

Four digit Miller index is sometimes used for hexagonal lattices. The idea is to have useful property: permutation of indexes gives an equivalent direction. It is mentioned in wikipedia, by the way. So you could start from there. Four-digit Miller indexes are never used for cubic structure.

Here h, k and ℓ are identical to the corresponding Miller indices, and i is a redundant index. This four-index scheme for labeling planes in a hexagonal lattice makes permutation symmetries apparent. For example, the similarity between (110) ≡ (11 2 0) and (120) ≡ (1 1 20) is more obvious when the redundant index is shown.
Hence (142) are the Miller Indices of the plane. Orientation of a crystal plane in a lattice is specified by Miller Indices. These are denoted as h,k & l (the plane is denoted as (hkl) ). These are defined as the reciprocal of the intercepts by the plane on the axes. This is an online tool to visualise a plane associated with a specific set of miller indices. In Figure 4, the beveled edges of the square faces have 5 parallel faces; check the summative properties of adjacent face Miller indices. How are the five faces related to each other?
