N2 - ABSTRACT. We show that in a model obtained by forcing with a countable support iteration of Mathias forcing of length U2, the distributivity number of "P(w)/fin is W2i whereas the distributivity number of r.o.(7'(ct')/fin)2 is u\. This answers a problem of Balcar, Pelant and Simon, and others.
