Models of Set Theory with Atoms another one in which a cardinal . exists such that .. These somewhat strange models are constructed like models of . (see the cumulative hierarchy introduced in Chap. .). However, instead of starting with the empty set (in order to build the cumulative hierarchy) we start with a set of . and define
