I am typing my summer report in overleaf and overleaf gives us to select from various kinds of projects (as an already made up format) and I selected Wright State Univ Thesis report format. Now in its preamble it is showing package
\amssymb but when I type
\rtimes it shows undefined control sequence. How can I fix this?
Here I am attaching the pic which shows the preamble-
Plese tell me how can I use
\amssymb as typing so many math symbols is getting impossible without it, now. I am 30% complete, so cannot rewrite it.
P.S.- I do note have any experience with latex and I am new to it.
