I need an extra index notation for the integral symbol .

I know the /displaylimits could modify the position of index notation, but I wonder how to add three index notation to an integral symbol?

The macro \inttriple, defined below, may do the job.

enter image description here

\documentclass{article} % or some other suitable document class
\usepackage{mathtools} % for '\mathclap' macro

%% define a new macro:
x &= \int_{0}^{\infty} \\
  &= \inttriple{\gamma}{0}{\infty} \\
  &= \inttriple{\text{hello}}{0}{\infty}
