Ramanujan

In "Hiding Place," Captain Bahadur Torrance from Ramanujan wears a turban bearing the Ship-and-Sunburst of the Polesotechnic League.

In Mirkheim, Free Hermetian commandos sabotage XT Systems in the city of Maharajah on Ramanujan.

In The Day Of Their Return, Chunderban Desai from Ramanujan has a spectacular holograph of Mount Gandhi in his office on Aeneas.

In A Knight Of Ghosts And Shadows, Dominic Flandry wears what he claims is the latest fashion in Dehiwala on Ramanujan: colourful, embroidered civilian garments and a turban held together by a plumed emerald brooch.

I think that that is all the information that there is about Ramanujan.
