Determining Miller Indices of High Index Planes

[beaverdam]

Hi,

can anyone explain how miller indices can be determined for high index planes?
For example, why is it that

(544) = (S)-[ 9(111) x (100) ]

I tried to figure it out but i could no find a pattern

Thx in advance

3-component Miller Indices are defined in terms of cubic unit cells. Go back to the definition of a Miller Index. For (544) = (S)-[ 9(111) x (100) ], I cannot answer because I don't know what S is.
