There is this algorithm I have to make
1 2 1 1 5 6 1 1 9 10 .....
what is the rule of the algorythm to do this ?

Position  1 2 3 4 | 5 6 7 8 | 9 10 11 12
          --------+---------+-----------
Sequence  1 2 1 1 | 5 6 1 1 | 9 10 ?? ??

Can you see a pattern?

Maybe always after 2 chars there are two '1's .
