Sorry if this is not the proper place to ask this question, but I cannot find related information from the help pages.
I wrote a comment on this post giving some extended and related data to help analyzing the question. Due to the large amount of numbers appeared as a sequence, I used \$ signs to quote the whole sequence of numbers. As a result, the comment (and all the previous comments under the same answer) has widened and part of the comments cannot be shown (they seem to be outside the webpage margin). Worse still, the delete button for the comment cannot be shown either, probably outside the margin as well. Is there any admin that I can ask for deleting that single comment? The comment is the one starting with $P_1(12)$. Thank you very much!
