  Galaxies are believed to be in one-to-one correspondence with simulated dark
matter subhalos. We use high-resolution N-body simulations of cosmological
volumes to calculate the statistical properties of subhalo (galaxy) major
mergers at high redshift (z=0.6-5). We measure the evolution of the galaxy
merger rate, finding that it is much shallower than the merger rate of dark
matter host halos at z>2.5, but roughly parallels that of halos at z<1.6. We
also track the detailed merger histories of individual galaxies and measure the
likelihood of multiple mergers per halo or subhalo. We examine satellite merger
statistics in detail: 15%-35% of all recently merged galaxies are satellites
and satellites are twice as likely as centrals to have had a recent major
merger. Finally, we show how the differing evolution of the merger rates of
halos and galaxies leads to the evolution of the average satellite occupation
per halo, noting that for a fixed halo mass, the satellite halo occupation
peaks at z~2.5.
