 # ordinal numbers of the bit positions set for a sequence of integers,

 # which are used for the rowid.  There are a total of 30 INSERT and

 # DELETE statements, so that we'll test both the segmentMerge() merge

 # (over the first 16) and the termSelect() merge (over the level-1

 # segment and 14 level-0 segments).
