Abstract
For the sixth-order equation of the K 2 hierarchy, we establish conditions for the existence of families of polar solutions, construct polynomial Hamiltonians and Bäcklund transformations, represent meromorphic solutions via a ratio of special entire functions, and give a criterion for the existence of rational solutions.
