There are THREE stereoisomers:
There is one MESO compound (RS = SR)
Then there are 2 enantiomers (SS and RR) which are mirror images but NOT superimposable (meaning different compounds)

Giving you a total of 3

There are two isomers, R, R and R,S. The S,S isomer is the same as the R,R. The S,R isomer is the same as the R,S

In simpler language, it is the cis and trans isomers.
