The same sort of analysis as we just went through with vector bundles shows that, H1(X, GL(n,O)) is equivalent to {isomorphism classes of locally free sheaves of rank n}. This is consistent with the previous association from vector bundles to locally free sheaves - so these notions are essentially equivalent. ' (G), etc. , then take the associated bundles.
