The second day of the conference began with a plenary talk by Prof. Mark L. Lewis from Kent State University, USA, who gave a detailed lecture on Self-normalizing Subgroups (Online). This was followed by an invited talk from Prof. Pudji Astuti of Institut Teknologi Bandung, Indonesia, discussing Mutually Commuting n-Tuples with Respect to an Automorphism, which provided insightful connections between automorphisms and group structure. After the morning coffee break, Dr. Manimaran from Vellore Institute of Technology, India, presented on Matrix-Based Representation of Z-Fuzzy Soft-Covering Multigranulation Fuzzy Rough Sets and Its Application to MAGDM Using AHP. His talk introduced fuzzy logic-based methods that intersect with group-theoretical perspectives.

The afternoon featured parallel sessions where researchers from around the world—both international and local—shared new results and ideas closely related to group theory. These sessions reflected the conference’s goal of promoting global collaboration and knowledge exchange within the field.
