We complete the classification of half-supersymmetric branes in toroidally
compactified IIA/IIB string theory in terms of representations of the T-duality
group. As a by-product we derive a last wrapping rule for the space-filling
branes. We find examples of T-duality representations of branes in lower
dimensions, suggested by supergravity, of which none of the component branes
follow from the reduction of any brane in ten-dimensional IIA/IIB string
theory. We discuss the constraints on the charges of half-supersymmetric
branes, determining the corresponding T-duality and U-duality orbits.
