Yes, and link it to the "co-" sequence of the values being repeated: 0, 2, 4, 6, 8, 10, -27, -64,...
(analogous to having two sequences for numerators/denominators, real/imaginary parts, etc)

> Dear seqfans,I’m in the process of submitting a few sequences whose difficult to predict features become apparent only when viewed in large, like as a graph. The sequences contain long parts composed of simple patterns which give no hint about the more dramatic behavior of the whole. Thus, there is a kind of representation problem in numeric form. For instance, one of the sequences starts like this:0, 0, 0, 0, 0, 0, 0, 0, 0, 2, 2, 4, 4, 6, 6, 8, 8, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, …,There are altogether 1166 tens.Instead of illustrating the nature of the sequence, as usually, with its first two or three hundred terms, a more informative way in this case would be to replace the pattern of tens by ..,10,<1164>,10, …, or similar. Extending the same notation to other long tautologies, say, longer than 10, we would get 0, 0, 0, 0, 0, 0, 0, 0, 0, 2, 2, 4, 4, 6, 6, 8, 8,10,<1164>,10, -27,<35>,-27, -64,<35>,-64,…etc. But this type of notation may not be in use in OEIS.Of course I can leave the sequence as it is and explain its nature in Comments. Any suggestions?Veikko (Pohjola V.J.)--Seqfan Mailing list - http://list.seqfan.eu/
