This study presents a quasi Curtis–Tits–Phan theorem applicable to symplectic groups by adapting Curtis-Phan-Tits theory to utilize pairs of almost opposite chambers corresponding under symplectic polarities. It explores the implications of this new approach for the recognition of symplectic groups, revealing connections to the simplification of certain geometries that emerge in the context of finite simple groups.
