Hello SeqFans,
can't find this seq K in the OEIS...
K=0,0,1,2,1,3,2,4,5,3,6,7,4,8,5,9,1,6,1,7,0,0,8,2,3,9,2,4,3,5,6,7,4,8,9,5,1,6,1,7,0,0,8,2,9,3,2,4,5,3,6,7,4,8,5,9,1,6,1,7,0,0,8,2,3,9,2,4,3,5,6,7,4,8,9,5,1,6,1,7,0,0,8,2,9,3,2,...
Rules:
- 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,...
9-9)
- Never start a new cycle before the
previous one has been completed.
Question:
At some point K has to enter into a loop,
I guess. But when and which loop?
Best,
É.
