I have studied stringy symmetries and compactifications when fluxes
are turned on. We have generated various new classical solutions
using these symmetries and have studied their spacetime properties.
Notable amongst them are the supersymmetric (D6,D8) brane bound-state
supergravity solutions with nonvanishing -field.
