  The magnetic Skyrmion is described by one control parameter and one length
scale. We study the two extreme limits of the control parameter - infinitely
large and vanishing - and find that the magnetic Skyrmion becomes a
"restricted" magnetic Skyrmion and an O(3) sigma model lump, respectively.
Depending on the potential under consideration, the restricted limit manifests
differently. In the case of the Zeeman term, the restricted magnetic Skyrmion
becomes a "supercompacton" that develops a discontinuity, whereas for the
Zeeman term to the power 3/2 it becomes a normal compacton. In both the lump
and the restricted limit the solution is given in exact explicit form. We
observe that the case of the Zeeman term squared, which can also be understood
as a special combination of the Zeeman term and the easy-plane potential -
realizable in the laboratory, the analytically exact solution for all values of
the coupling - including the BPS case - is also of the lump type. Finally, we
notice that certain materials (e.g. Fe$_{1-x}$Co$_x$Si or Mn$_{1-x}$Fe$_x$Ge)
have a rather large control parameter $\epsilon$ of order 100, making the
restricted limit a suitable rough approximation.
