The GAP 4 package `ferret' ========================== Ferret is a reimplementation of parts Jeffery Leon's Partition Backtrack framework in C++, with extensions including: * Ability to intersect many group simultaneously. * Improved refiners based on orbital graphs. This package currently supports: * Group intersection. * Stabilizing many structures including sets, sets of sets, graphs, sets of tuples and tuples of sets. This package can be used by users in two ways: * When the package is loaded many built-in GAP functions such as 'Intersection' and 'Stabilizer' are replaced with more optimised implementations. This requires no changes to existing code. * The function 'Solve' provides a unified interface to accessing all the functionality of the package directly. This package needs to be built. This can be done by entering GAP's pkg directory and running ../bin/BuildPackages.sh ferret* (Running ../bin/BuildPackages.sh will build all packages, including Ferret)
