Omega, Sadhana, and PI Polynomials of Quasi-Hexagonal Benzenoid Chain
Counting polynomials are important graph invariants whose coefficients and exponents are related to different properties of chemical graphs. Three closely related polynomials, i.e., Omega, Sadhana, and PI polynomials, dependent upon the equidistant edges and nonequidistant edges of graphs, are studi...
