Hi Binyamin,
They match because most of the leaf rows (106536) are deleted leaf rows
(106533) meaning you only have *3* non deleted leaf rows.
Basically your table has undergone a somewhat dramatic shrinkage in size.
If you want to learn a thing or two about indexes, take a took at a recent
presentation of mine at
www.actoug.org.au/Downloads/oracle_index_internals.pdf
Regards
Richard
