Abstract. We prove that any permutation p of the plane can be obtained as
a composition of a xed number (209) of simple transformations of the form
(x; y) ! (x; y + f(x)) and (x; y) ! (x + g(y); y), where f and g are arbitrary
R ! R functions.
As a corollary we get that the full symmetric group acting on a set of
continuum cardinal is a product of nitely many (209) copies of two isomorphic
Abelian subgroups.
We investigate what transformations of the plane we can get by (nitely many)
vertical and horizontal \slides", which we dene as follows.
Denition 1. By a vertical (resp. horizontal) slide we mean an R 2 ! R 2 map of
the form (x; y) ! (x; y + f(x)) (resp. (x; y) ! (x + g(y); y)), where f (resp. g) is
