  In this paper we shall elucidate some of the effects of the quartic
quasitopological term for Lifshitz-symmetric black holes. The field equations
of this theory are difficult to solve exactly; here we will use numerical
solutions both to verify previous exact solutions for quartic quasitopological
AdS black holes as well as to examine new quasitopological Lifshitz-symmetric
black hole solutions, in order to determine the effect of the quartic coupling
parameter on the black hole's thermodynamic behavior. We shall find that the
quartic parameter controls solutions very similarly to the cubic parameter,
allowing for the construction of a theory with another free parameter which may
find meaning in the phase transition behaviour of a gauge/gravity context.
