[OS X TeX] Ordering index entries

[Luis Sequeira]

The makeidx package allows you to decide how a given index entry is sorted. 
This is done with a syntax like 

 \index{how at what}

(in that the key entered into the index is “what” but it appears in the alphabetical order corresponding to “how”)

The default order is alphabetical, so I think you meant “numerical”, but here is a way you can easily sort numerically:

\index{Base (of a numeral)!base 04 at base 4}
 \index{Base (of a numeral)!base 06 at base 6}
 \index{Base (of a numeral)!base 10 at base 10}
 \index{Base (of a numeral)!base 60 at base 60}

This will show:

Base (of a numeral)
	base 4, …
        base 6, …
 	base 10, …
	base 60, …

as you require, by using “base 04” “base 06” “base 10” and “base 60” to do the ordering.
