G-Sets¶
- class sage.categories.g_sets.GSets(G)[source]¶
Bases:
Category
The category of \(G\)-sets, for a group \(G\).
EXAMPLES:
sage: S = SymmetricGroup(3) # needs sage.groups sage: GSets(S) # needs sage.groups Category of G-sets for Symmetric group of order 3! as a permutation group
>>> from sage.all import * >>> S = SymmetricGroup(Integer(3)) # needs sage.groups >>> GSets(S) # needs sage.groups Category of G-sets for Symmetric group of order 3! as a permutation group
TODO: should this derive from Category_over_base?
- classmethod an_instance()[source]¶
Return an instance of this class.
EXAMPLES:
sage: GSets.an_instance() # indirect doctest # needs sage.groups Category of G-sets for Symmetric group of order 8! as a permutation group
>>> from sage.all import * >>> GSets.an_instance() # indirect doctest # needs sage.groups Category of G-sets for Symmetric group of order 8! as a permutation group
