[Wien] LMMAX again

[jrosad2]

Hello,

I think the lm list looks okay, for (+-l,l-2m) the sets should be (1,1),(-1,1) 
for m=0 and for m=1 gives (1,-1) and (-1,-1)... I'm not an expert but I've 
negative m values are not valid and (-1,0), (-2,0),...(-n,0) never seem to be 
included in the lm-list, though I have no idea why.  Maybe someone can 
explain?

>Hello,

doesn't matter, but I'm not sure (perhaps the last value is used as 'maximum' 
somehow)?  Better play safe and put them in the right order, unless someone 
else tells us it's okay not to.
>How I got them : 1/ I remember finding something about it in the old archives 
which gave some examples; 2/ for pointgroup "1" it's not very difficult, 
obviously ;-).

group, since I definitely took that from wien and only added l=7 tot 10 
myself.  But who knows, it's a file I haven't used in a while.

>In your example, the second sort has point group "m", so its LM combination 
should take (+-l,l-2m). As "l" takes value 1, there are supposed to have four 
sets of LM, that is, (1,0),(1,1),(-1,0) and (-1,1), I think. However I can't 
find (-1,0) in the corresponding line (second line) in your .in2 file. Am I 
right?

the default value 6 to 10 in the source code directly? If I add it by hand, 
does the order of the LM list matter?

>	Dear WIEN community,
>
>	A couple of days ago, I asked a question about LMMAX here and Kevin's answer 
helped me a lot. However, when I try to add LM list manually, I meet problems. 
For example, with a site symmetry "2/M", as listed in Table7.39 in usersguide, 
the LM combination should be (+-2l,2m). So I try to set l=0,1,2,3, (m=0,1,...l 
for each l) in order to reproduce the default lmmax up to 6, and I get 19 LM 
combinations manually. However, I only got 16 LM combinations after I run 
"SYMMETRY". Those three (-2,0) (-4,0) and (-6,0) do not show up in the LM list 
obtained from SYMMETRY. What's the problem here? Or I did something wrong? 
Your reply will be highly appreciated.
