The fragmentation of relativistic $^{16}\mathrm{O}$ projectiles in nuclear emulsion into projectile fragments of Z\ensuremath{\ge}2 has been investigated. Production rates, charge, and multiplicity distribution of such projectile fragments and their dependence on target-fragment multiplicities have been obtained. The width of the momentum distribution of He (Z=2) projectile fragments as well as the average number of target fragments is found to decrease with increasing He multiplicity. These dependences are, within errors of measurement, the same for E/A=2.1, 14.6, 60, and 200 GeV, and to that extent satisfy the condition of limiting fragmentation.
