I am new to understanding Miller indices (its never been covered in a class that i have taken etc) and there is a notation that i am seeing in the scientific literature that i don't understand. -Its the notation used after the (h,k,l) numbers. here are a few examples (I put in bold print the bit that I don't understand):(adsbygoogle = window.adsbygoogle || []).push({});

Ge(100)-2 x 1

Ge(111)-2 x 8

S/Ge(111)-2 x 2

I have looked at various intro to miller indices type of sites, but none of them make any mention of what the notation means after the (h,k,l) notation.
