EDGE-WIENER INDEX OF LEVEL-4 SIERPINSKI SKELETON NETWORK

We study the edge-Wiener index of the rank-[Formula: see text] skeleton networks associated with the level-4 Sierpinski triangle. Recursive relations are derived for the count of each pattern, and an explicit formula is obtained for the edge-Wiener index of the level-4 Sierpinski skeleton networks. Our result shows that the finite-pattern method remains effective for exact edge-distance computations on higher-order self-similar networks.
