N2 - Let G be a countable saturated model of the theory Im of divisible m-rigid groups. Fix the splitting G1G2..Gm of a group G into a semidirect product of Abelian groups. With each tuple (n1,.. , nm) of nonnegative integers we associate an ordinal α = ωm−1nm+.. + ωn2 + n1 and denote by G(α) the set G1n1×G2n2×…×Gmnm, which is definable over G in Gn1+…+nm. Then the Morley rank of G(α) with respect to G is equal to α. This implies that RM (G) = ωm−1 + ωm−2 +.. + 1.
