In this paper, we are concerned with the study on metric spaces withcomplexity of the smallest infinite ordinal number. We give equivalentformulations of the definition of metric spaces with complexity of the smallestinfinite ordinal number and prove that the exact complexity of the finiteproduct of wreath product is the smallest infinite ordinal number.Consequently, we obtain the complexity of (ZwrZ)wrZ is w+1.
