Narrative:

Our pre departure clearance for departure was the loop 4. When asked by ATC to go to intersection on the departure; we said it wasn't on the flight plan. When we examined closely the pre departure clearance out of 10000 ft; there was a revised departure of oshnn instead of loop. The crew did what was asked by ATC.
