Hello SeqFans,
can't find this seq K in the OEIS...

- all integers of K are >= 0 and <= 9
- there are d integers between each pair of successive d integers
- K was extended trying always to insert the smallest pair of integers not
yet inserted in K
- when the first 9-9 pair of integers has
been inserted, start a new cycle with 
the second set of pairs (0-0,1-1,2-2,... 
- Never start a new cycle before the
previous one has been completed.

At some point K has to enter into a loop,
I guess. But when and which loop?
