The program is Aarseth's simplest nbody code (contained in Binney and Tremaine, 1987, no regularization or nearest neighbors). The input is a Hubble expanding cartesian lattice, w/ 925 pts, GMtot=1, expansion factor = 6 (omega = 1.2). Long version followed for 60 time units, short version for 5. Results are summarized in Table E.2
