# Does Tex, LaTeX support 'Tetration' & 'super square root' notations? [duplicate]

https://en.wikipedia.org/wiki/Tetration

in TeX, LaTeX

It seems to me it does not support Tetration symbols??

• (1) Welcome, (2) Erh, all those images on the wiki page is made using latex. Please provide information about what you have done so far to conclude that it should not be supported – daleif Jun 30 '16 at 11:13
• leftidx,mathtools and tensor packages offer macros for this purpose. – percusse Jun 30 '16 at 11:28
• The wikipedia article you quote uses TeX notation (inside [itex] tags), you can just copy it from there (use the "edit" tab in wikipedia to see the source code of the page). – jknappen Jun 30 '16 at 12:08
