Number(s) not in SEQs?

[Robert G. Wilson v]

Et al,

        I am assuming here that we are also excluding sequences such as 
A000040: the Primes
and A002808: the Composites; and other sequence (Betty seq.) which are 
complimentary.
Also I assume that we need to exclude sequences of the natural numbers 
in various bases,
Gray code, etc.

Bob.
