If you mean unbranched carbon chain number of pairs of enantiomers is 24, number of all stereoisoners is 25
For cyclic forms you should consider one more asymmetric carbon atom
and eventually take into account furanoses and pyranoses. This give you a total number up to 96 pairs of enantiomers (most of them are also called anomers)
