On a certain OEIS convention

Question

Do you know what it is that those numbers which appear in the upper-right angle of the blue-box mean?

I presume they have to do with a certain ranking of the sequences within the site, but I am not sure.

Thanks in advance for your replies.

Answer 1

Per the OEIS hints page:

The meaning of the little numbers at the right of the blue bar. For example, +30 and 1086 for A000045.

The +30 is the sequence's query score -- how well it matches the query.

You get 100 points for matching ordering (for example, having 1 3 5 not 1 2 3 4 5 when the query is 1 3 5).

You get 10 points for matching terms in certain lines (for example, sequence data counts more, and sequence number counts a lot more).

The 1086 is the number of sequences in the database that reference the given sequence.

The "relevance" sort is by query score, with ties broken by reference count.
