Oracle Database Discussions

My oracle is 10g, create table statement is below:

CREATE TABLE S005.Test

(

  aaa  CHAR(1)

)

PCTFREE    0

STORAGE    (

            FREELISTS        10

            FREELIST GROUPS  20

           )

LOGGING

NOCACHE

NOPARALLEL

NOMONITORING;

After execute this sql, i query USER_TABLES table but FREELISTS and FREELIST_GROUPS fields show nothing,

I think value of FREELISTS should be 10, and FREELIST_GROUPS should be 20. How to retrieve these values?

Thanks a lot
