  Developing a system of parallel non-linear iterations, we establish the
consistency of $\mathfrak{b}<\mathfrak{s}<\mathfrak{d}<\mathfrak{c}$ where
$\mathfrak{b}, \mathfrak{d}, \mathfrak{c}$ are arbitrary subject to the known
ZFC restrictions and $\mathfrak{s}$ is regular. By evaluating other invariants
we achieve also the constellations
$\mathfrak{b}<\mathfrak{r}<\mathfrak{d}<\mathfrak{c}$,
$\mathfrak{b}<\mathfrak{e}<\mathfrak{d}<\mathfrak{c}$ and
$\mathfrak{b}<\mathfrak{u}<\mathfrak{d}<\mathfrak{c}$.
