This is closely related to sequences which contain almost all integers, 
but the first term in the sequence is quite large. Examples include 
A171102 and A121977.

I would be particularly interested to find examples of either of these 
properties that are not base sequences.

Subject: [seqfan] Rather interesting sequence


I think that any example of a sequence with almost all zero terms, but 
such that
the first zero term occurs for very large n, is rather attractive. As 
an
example, I would like to mention the sequence A232897. The first 
positive
position n when a(n)=0 is more than 10^9. However, the seqence has 
almost all
zero terms. Are there other such type examples in OEIS?

Regards,
Vladimir
