Addition of velocities in special relativity is not straightforward: the parallelogram addition law does not apply because velocity addition is neither commutative nor associative. This package furnishes functionality to work with Lorentz transforms and the gyrogroup structure of threevelocities. For general relativity, see the 'schwarzschild' package.
