The authors show that the isosceles synchronous periodic solutions of the 3-body Stokeslet problem are elliptic near the equilibrium. A calculation going beyond group-theoretic considerations is given to decide the stability of the isosceles synchronous and the instability of the isosceles asynchronous normal modes. Moreover, it is shown that subharmonic solutions bifurcate from these elliptic modes...
