We investigate the invariance properties, nontrivial conservation laws and interplay between these notions that underly the equations governing Stokes’ ﬁrst problem for third-grade rotating ﬂuids. We show that a knowledge of this leads to a number of different reductions of the governing equations and, thus, a number of exact solutions can be obtained and a spectrum of further analyses may be pursued.
