The illustration is extremely useful, but...

The drawings for L=2, M= +2 and M= -2 (third line, leftmost and rightmost) are identical and therefore cannot both be correct.

I assume that one of them should be rotated 90 degrees about the vertical axis; alternately, all colors could be changed. — Preceding unsigned comment added by Stenboj (talk • contribs) 19:48, 12 April 2017 (UTC)
