Which title distinguishes Chandragupta I from his Gupta predecessors Sri Gupta and Ghatotkacha in the dynasty’s inscriptional genealogy?

Explanation

Maharajadhiraja, meaning great king of kings. Sri Gupta and Ghatotkacha are described as maharajas, whereas Chandragupta I is described as maharajadhiraja. His successor was Samudragupta; Kumaragupta I belonged to a later generation. This does not claim that Chandragupta I was the first Indian ruler ever to use the title.
