My developer's table creation scripts have some CREATE TABLE options I've never come across before. He's using some tool to generate scripts and they've added vanilla storage clauses (all identical - initial extent 100K , next extent 100K etc) to every table regardless of use etc.

At the end every table has 3 other clauses:

FREELISTS 1
FREELIST GROUPS 1
BUFFER_POOL DEFAULT

what do they mean in this CREATE TABLE context?
