Abstract
Explicit formulas for computing the Zhang-Zhang polynomial of cyclo-polyphenacenes, presented by Guo et al. (J. Math. Chem. 46:347, 2009) are found to be erroneous. In the present comment, a corrected version of Theorem 4. 2 is given. The new formulation has been extensively tested by comparison with the Zhang-Zhang polynomials computed by brute force using a new, completely automatized computer code.
