Let chi be the minimum cardinal of a subset of 2^omega that cannot be madeconvergent by multiplication with a single Toeplitz matrix. By an applicationof creature forcing we show that s<chi is consistent. We thus answer a questionby Vojtas. We give two kinds of models for the strict inequality. The first isthe combination of an aleph_2-iteration of some proper forcing with addingaleph_1 random reals. The second kind of models is got by adding delta randomreals to a model of MA_{< kappa} for some delta in [aleph_1,kappa). It was aconjecture of Blass that s=aleph_1<chi=kappa holds in such a model. For theanalysis of the second model we again use the creature forcing from the firstmodel.

The splitting number can be smaller than the matrix chaos number
