We present some results concerning the triple-Regge domain of inclusive distributions. We show that exchange degeneracy requires the equality of the proton-Reggeized-$\rho$ and the proton-Reggeized-$A_2$ total cross sections, and then we extract this cross section from data on the reaction $K^{+}p\to K^0+$ anything. This cross section turns out to be of the same order as physical meson-proton cross sections for a range of Reggeon mass. We derive relationships between different inclusive distributions, such as $\mathrm{pp}\to \mathrm{pX}$, $K^{+}p\to K^{+}X$, and $K^{+}p\to K^{0}X$, and get good agreement with data. We suggest that other inclusive distributions, such as $\mathrm{pp}\to {\pi }^{+}X$, may be calculated using as input only our knowledge of two-body reactions.
