Abstract
The principal application of a general theorem proved here shows that for any choice 1≤m≤n≤p of integers there exist metric spacesX andY such that the initialk-segments of their clones of continuous maps coincide exactly whenk≤m, are isomorphic exactly whenk≤n, and are elementarily equivalent exactly whenk≤p.
