%X This exploration of solutions for the orbits of Local Group galaxies under the cosmological initial condition of growing peculiar velocities and fitted to measured distances, redshifts, and proper motions reveals a considerable variety of histories allowed by present constraints. The solutions also point to computations and measurements at the current level of precision that may lead to a more accurate picture of Local Group dynamics, or perhaps point to adjustments of our simple picture of the arrangement of mass within the Local Group.
