If Extent Constraint relief is used, then the max is 7257. Then there is the relatively new feature called Extent Consolidation. If a new extent is needed, the system finds an available extent according to all the previously discussed limits (per volume, max number of voumes, etc.). If this new extent begins exactly at the next track after the end of an already allocated extent, then the new extent is consolidated with the one already allocated. This does not mean you end up with more than 4080 (or 7257) total extents, but it does mean that you may take a trip through data set extend many more times than you end up with distinct extents to show for the trips.
