Step by step:
1 - X
2 - [
3 - i
4 - , (, or ; which one is your argument separator)
5 - j

> X[i,j

By the rule of the Syntax,
i.e: by length ... NOT by index.

Hi. No practical way in SMath, but with Unicode characters. Search for 'cero' in your language in windows charmap, copy and paste.

To do it without artifice you would have to have a function, like in Mathematica: https://reference.wolfra...age/ref/Superscript.html

Best regards.
