Ferret is a reimplementation of parts of 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 optimized implementations. This requires no changes to existing code.

• The function 'Solve' provides a unified interface to accessing all the functionality of the package directly.
