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

# which are used for the rowid.  There are a total of 31 INSERT,

# UPDATE, 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 15 level-0 segments).
