I would like to typset something similar to the symbol used for the "generalized spherical harmonics". This involves placing an array of dots above a letter. The array will have two columns, and the number of dots in each column can be different. I have tried the following, but it looks awful:
$\overset{\begin{matrix} . & \ \\ . & . \end{matrix}}{T}$
I would rather not have to fiddle with the array spacing manually, is there any way to do this simply? If not, how would I do it at all (even if it requires manual array spacing)?
An example of what it's supposed to look like can be found here (its the T symbol with the dots above it, but it shouldn't look like a triangle, it should distinctly be two columns with two dots on the left and one on the right):

Here is a possible way
I have defined only three combinations, you can say
\gsh{.&.&.&.}
for getting four dots (or define\gshfour
).New version
You use
\gshsym
for "short" superscripts that don't go beyond the letter to which they are overset,\gshsym*
for wider superscripts.
