  The Skyrme crystal is built up of repeating units similar to the cubic
Skyrmion of baryon number 4. Using this as guide, we construct new Skyrmion
solutions in the massive pion case, with various baryon numbers up to 108. Most
of our solutions resemble chunks of the Skyrme crystal. They are constructed
using a multi-layer version of the rational map ansatz to create initial
configurations, which are then relaxed numerically to find the energy minima.
The coefficients of the rational maps are found by a geometrical construction
related to the Skyrme crystal structure. We find some further solutions by
numerical relaxation of clusters composed of baryon number 4 Skyrmions.
