configuration to each chirality center in the additional isomers.
Indicate the stereochemical relationship (diastereomers,
enantiomers, meso compounds) between the first isomer and each of
the others. The configuration for the Fischer Projection has been
omitted, since stereochemistry can be determined from a 2-D
