We prove that this obtained formula is better than the formulas, which are previously presented. Also, we evaluate the coefficients for any limited power of  without depending on the number of circles, and we find the Wiener index and average distance for this structural. On the other hand, we build a MATLAB program to evaluate the Wiener polynomial coefficient, Wiener index, and average distance. 2024 2024 15 21 10.54216/GJMSA.0110202 https://www.americaspg.com/articleinfo/33/show/3198
