It is not entirely clear whether these two galaxies are interacting with each other
According to the measurements in the current databases for NGC 2672 - right galaxy (http://ned.ipac.caltech.edu/byname?objname=NGC+2672&hconst=67.8&omegam=0.308&omegav=0.692&wmap=4&corr_z=1) and NGC 2673 - left galaxy (http://ned.ipac.caltech.edu/byname?objname=NGC+2673&hconst=67.8&omegam=0.308&omegav=0.692&wmap=4&corr_z=1), the two galaxies are at different distances from Earth, although measurement errors must also be considered here.
However, it may also be that the two galaxies rotate around each other at a large distance, and the difference in redshift is caused by the Doppler effect.

Arp 259 consists of three galaxies.
The first two galaxies form NGC 1741 shown (left part of the large cluster). Here the upper part (bright blue area) is PGC 16573, the lower horizontal part is 2MASXI J0501387-041533.
The third galaxy is the right part and is called PGC 16570 (NGC 1741B).
Arp 259 belongs to HCG 31.
According to the original papers of Hickson PGC 16571 (small galaxy above PGC 16570) belongs to HCG 31.
In Wikipedia and SIMBAD HCG 31E (just below NGC 1741, the small blue dot), HCG 31F (small blue galaxy right below the star) and IC 399 (galaxy diagonally left below) are also included.
