I'm not certain what you want to do with this. Mathematica usually doesn't let "bare" comma separated items stand by themselves.

If you are going to use your list of comma separated items within some function call then perhaps this will help you.

In[1]:= (listofindices={};
For[s=1,s≤3,s++, listofindices=Append[listofindices,{Subscript[n,s],0,3-1}]];
For[s=3+1,s≤7,s++,listofindices=Append[listofindices,{Subscript[n,s],0,5-3}]]);
listofindices

Out[2]= {{Subscript[n, 1], 0, 2}, {Subscript[n, 2], 0, 2}, {Subscript[n, 3], 0, 2}, {Subscript[n, 4], 0, 2}, {Subscript[n, 5], 0, 2}, {Subscript[n, 6], 0, 2}, {Subscript[n, 7], 0, 2}}

In[3]:= f[Sequence@@%]

Out[3]= f[{Subscript[n, 1], 0, 2}, {Subscript[n, 2], 0, 2}, {Subscript[n, 3], 0, 2}, {Subscript[n, 4], 0, 2}, {Subscript[n, 5], 0, 2}, {Subscript[n, 6], 0, 2}, {Subscript[n, 7], 0, 2}]

But you should be able to accomplish the same thing with f@@%
