摘要：
We construct continuum many nonisomorphic א0-categorical posets which are 3- and not 4-homogeneous. Variants of our construction yield 2- and not 3-homogeneous posets, and yield as many non-א0-categorical posets with the same degree of homogeneity. These examples answer questions of Droste and Macpherson. © 1993.
