I've tried and worked. However, in my program, I would like to calculate dimensions, so sometimes I have 1, 2 or infinite -dimensional. I currently use 'cat' to combine infinite and -dimensional, and looking for some better display like infinite symbol. So, is there no other way to get this symbol instead of using MathMLViewer?
