almost identical sequences in OEIS

Hello!

Does OEIS distinguish sequences that coincide for many initial terms? Or sequences that coincide for *all known* terms but *not known* to be  equal?

Previously, I mentioned sequence A000079 which is the powers of 2 by the definition. At the same time it is said to be the "least deficient numbers". Indeed, all the powers of 2 are least deficient numbers but it is *NOT* known if there exists a least deficient number not being power 2 (so it might exist implying that the sequences are different).

Currently, I'm interested in sequence of such n that give local minimum for sequence A004125, i.e., such n that A004125(n-1)>A004125(n) and A004125(n)<A004125(n+1). Sequence of such n coincide with sequence A023196 for the first 1014 terms. Then there appears number 4095 which is an element of A023196 but not of a new sequence.

So I wonder how can this new sequence be added to OEIS? It seems unreasonable to keep all first 1014 terms to distinguish the sequences. Of course, I can add a sequnce which is a set difference of the two (and I'll do so) but I would like somehow to mention the original sequence as well.
