Abstract
We calculate the T=0 phase diagram of an integrable anisotropic three-leg q uantum spin tube connected to the SU(8) algebra. We find several quantum ph ase transitions for antiferromagnetic rung couplings. Their locations are c alculated exactly from the Bethe ansatz solution and we discuss the nature of each of the different phases.
