This generalizes previous results, in which the automorphism was required to be free. As an application, we show that group class="mathmlsrc">class="formulatext stixSupport mathImg" data-mathURL="/science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0001870815301250&_mathId=si2.gif&_user=111111111&_pii=S0001870815301250&_rdoc=1&_issn=00018708&md5=b8deeaf9c47ba11ff8fb57d62af08b60" title="Click to view the MathML source">C⁎class="mathContainer hidden">class="mathCode">-algebras of certain non-nilpotent groups have finite nuclear dimension.
