Keywords:
model of ZFC; generic extension; rigid Boolean algebra; hereditary $M$-definable
Summary:
In this note, we show that the model obtained by finite support iteration of a sequence of generic extensions of models of ZFC of length $\omega$ is sometimes the smallest common extension of this sequence and very often it is not.
