We prove that the criterion for Markov equivalence provided by Zhao et al. (2005) may involve a set of features of a graph that is exponential in the number of vertices.

Graphical methods for efficient likelihood inference in Gaussian covariance models
Mathias Drton, Thomas S. Richardson
In graphical modelling, a bi-directed graph encodes marginal independences among random variables that are identified with the vertices of the graph. We show how to transform a bi-…
