In this question:, Customising glossary group titles , it have been instructed how to redefine group names of glossaries printed from the glossaries package using the function
\newcommand*{\Agroupname}{Roman letters}
\newcommand*{\Ggroupname}{Greek letters}
How to do the same thing for the "Numbers" group ?
Here is a MWE:
\documentclass{article}
\usepackage[
xindy
]{glossaries}
\usepackage{glossary-mcols}
%% glossary entries
\newglossaryentry{commut}{sort={0},name={\ensuremath{[~,~]}},
description={Commutator}}
\newglossaryentry{L}{sort={aL},name={\ensuremath{\mathcal{L}}},
description={lift function}}
\newglossaryentry{CL}{sort={aCL},name={\ensuremath{C_L}},
description={lift coefficient}}
%
\newglossaryentry{alpha}{sort={galpha},name={\ensuremath{\alpha}},
description={angle of attack}}
\newglossaryentry{beta}{sort={gbeta},name={\ensuremath{\beta}},
description={sideslip angle}}
%
\newglossaryentry{fs}{sort={sfs},name={\ensuremath{\infty}},
description={free-stream condition}}
\immediate\write18{makeglossaries \jobname}
\makeglossaries
% Define glossaries groups
\newcommand*{\Agroupname}{Roman letters}
\newcommand*{\Ggroupname}{Greek letters}
\newcommand*{\Sgroupname}{Subscripts}
