  We show that the same wrapping rules that have been derived for the branes of
IIA and IIB string theory also apply to the branes of the toroidally
compactified heterotic string theory. Moreover, we show that applying these
wrapping rules to the IIA theory compactified over K3 is consistent with the
well-known duality between the heterotic string theory compactified over T^4
and the IIA string theory compactified over K3. We derive a simple rule that
relates, in any dimension, the T-duality representation of the branes of the
toroidally compactified heterotic theory to the relevant R-symmetry
representation of the central charges in the supersymmetry algebra. We show
that, in the general case, the degeneracy of the BPS conditions of the
heterotic branes is twice as large as that of the branes of IIA and IIB string
theory.
