One, SF97710 is a cover letter only.  It lists what PTF's are on the 
latest cume.  Therefore it will not appear on SF98035.
SF97710 does not list any group ptf numbers.  If you search that link for 
SF99 you will not see any group PTF's listed.  What you will see are 
individual ptf's that are listed that may or may not be on a particular 
group.  I did a little spot checking and the PTF's listed on the other 
link, that are in TR6, are listed in this cume.
What is not up to date is the documentation on the latter link.  It was 
last updated in February, which was before the cume came out.  Let me give 
you some details.
If I look at
http://www-912.ibm.com/s_dir/sline003.NSF/554c38c4848b77f2862567bd0046e003/85fc5e8ebc0523048625779900742abc?OpenDocument
you will see
-------------------------------------------------

...
cume package 1000 implies that MF55886 is on TR6 but is not on a cume. 
However, if we look at the cume cover letter at
http://www-912.ibm.com/s_dir/sline003.nsf/2d3aff1c6b4d6ce086256453000d971e/d37adbbbf29e07eb8625770a005b18b3?OpenDocument
and search that for MF55886 you will see that MF55886 came out in cume 
3037
MF55886  3037  11/01/12 LIC-MEDIA-TAPE Add support for 3580-006
So if IBM would update the cover letter for SF99006 then this
MF55886     02/12/13    MA42205    5770999  1000
would become
MF55886     02/12/13    MA42205    5770999  3037
Understand?
