Through numerical simulations we study N-soliton scattering (N=3,4) in the (2 + 1)-dimensional CP¹ model with periodic boundary conditions. Solitons colliding from symmetrical configurations scatter at π/N, as observed in the usual model with standard boundary conditions. When the initial configurations are not symmetric the angles differ from π/N. We describe our observed patterns based on a properly formulated geodesic approximation.
