For the turn of the millennium, I compiled some sequences about the 
database of sequences.  Here are some of them:

---------------
Positive integers not explicitly in the database before 1/1/2001

offset 1

6407,6492,7088,7194,7724,7795,7835,8045,8267,8547,8637,8662,8795,
8847,8919,8934,9022,9095,9230,9266,9335,9404,9414,9454,9580,9645,
9731,9734,9756,9774,9783,9846,9847,9885,9905,9927,9930,9935,9978

--------------

First sequence in which n appears [as of 1/1/2001].

offset 0

4,1,1,1,1,1,1,3,3,3,1,6,1,1,1,1,6,6,6,8,10,25,8,11,10,8,14,9,8,15,10,
8,9,25,8,26,10,15,9,26,8,15,10,8,11,27,9,15,10,8,1,1,1,15,9,26,13,26,
8,15,10,26,26,11,8,24,10,26,25,26,8,27,27,19,27,27,8,41,14,28,17,28,8

----------------
number of sequences in which n explicitly appears, before 1/1/2001

offset 0

16013,37969,23764,20132,18572,16449,15519,14441,13696,12495,9834,

-----------------
Number of times n explicitly appears in the database before
1/1/2001, counted with multiplicity.

offset 0

168259,221170,113144,77176,69111,56869,52980,46484,45696,39904,17017,

-------------------
Most frequent non-negative integers explicitly appearing in the
database before 1/1/2001, counted with multiplicity.

offset 1

1,0,2,3,4,5,6,7,8,9,10,12,11,13,16,14,15,18,17,20,24,19,21,30,22,23,

----------------
frequency of above

offset 1
