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.

It seems to me that the meaning of those numbers is nowhere to be found in the FAQ for the OEIS. – Jamai-Con Feb 09 '18 at 00:48

2Neil Sloane sent out an email today saying there is a bug in ranking algorithm of the new version of the OEIS. This probably explains why the number you're seeing is so funny. – Peter Kagey Feb 09 '18 at 02:09

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.
