Auto-generated structures by pymatgen

Hi, everyone, i was wondering that all crystal is composed by the space group and the element. Can we auto-generated the all structures when i specify the space group and elements? I have read the document of the pymatgen.symmetry. I thought there must be the way to do it by pymatgen, but i can’t figure it out, Can anyone help?
P.S. I apologise for my lack of knowledge on space groups.

Many thanks
