[edit] HKL / LMN

The notation "lmn" is new for me. What is the difference to "hkl"? SietskeEN 13:35, 19 July 2007 (UTC)

Um, isn't that like asking the difference between "x" and "y"? They are just variable names, representing integers. The choice of letters is pretty irrelevant — Miller indices are a positional notation, so only the position of the letters and the surrounding brackets matter. —Steven G.

Ok, thanks! SietskeEN 20:20, 19 July 2007 (UTC)

There is a certain relevance in that if one convention is widely dominant that one should prevail. This is the first time I have seen 'lmn' used. Obviously I am a fairly small sample, but you might want to look at other sites. —Preceding unsigned comment added by 131.111.195.8 (talk) 18:24, August 25, 2007 (UTC)

Have just done a test on google, the entry: hkl miller indices returns 85 500 results, lmn miller indices returns 23 600 results.

[edit] Simplification

I am planning to restructure this article further. I think the reciprocal lattice should get less attention, certainly in the lead and in the beginning of the article. (I had a student who tried to understand Miller indices and looked it up here on wikipedia, and did not find it helpful at all.) /Pieter Kuiper 07:56, 9 October 2007 (UTC)

[edit] Ambiguous 3D Coordinate System

Given the ambiguity of left-handed vs right-handed 3D coordinate systems, I think image depicting miller planes should be altered to reflect which is the y and which is the x-axis. Anybody want to take this on? In my mineralogy class and textbook, only the right-handed system is used so the unlabeled left-hand coordinates on the illustration were really confusing at first. It's important to realize that people from multiple disciplines (not just engineering) could be looking at this article, so a little clarification could go a long way in making this article more accessible.

Which image are you looking at? As far as I can tell, all of them are right-handed, and all of them are labelled sufficiently to determine this fact. (However, one of them misspells "plane" as "plan", which should be fixed.) —Steven G. Johnson (talk) 16:53, 16 February 2008 (UTC)
