Summary: In this paper, we investigated the upper bounds of \(|a_{3}-\mu a_{2}^{2}|\), \(\mu\) real, for a subclass of generalized Sakaguchi type functions of the form \(f(z)=z +\sum_{n=2}^\infty a_{n}z^{n}\), in the unit disc \(E=\{z:|z|<1\}\). Results due to various authors follows as special cases.
