Ferromagnetism of the single band Hubbard model at I = CX) is analyzed numer-ically. The lowest energies at given electron number and total spin are calculatedfor various finite lattices, such as 3 x 4 square lattice, 2 x 2 x 3 simple cubic latticeand triangular lattices. It is found that the three-site exchange is irnportant forthe strong ferromagnetism.
