GAP Manual: 51.5. Parametrized

Parametrized( list )

returns the parametrized cover of list, i.e. the parametrized map with smallest indeterminateness that contains all maps in list. Parametrized is the inverse function of ContainedMaps in the sense that Parametrized( ContainedMaps( paramap ) ) = paramap.
