The authors show that if a finite translation plane \(\pi\) admits a double-Baer group, then it also admits double retraction. Conversely, if \(\pi\) admits double retraction, then \(\pi\) admits a double-Baer group or a double-homology group. Some new examples of planes admitting double-Baer groups are also presented.
