Hello SeqFans,
Runs of digits of size a(n), which start with a(n) and sum up to a(n):
R = 1,10,11,12,20,110,111,112,13,21,100,101,13,15,16,17,18,19,22,23,24,25,26,27,30,102,a,...
(a is 10^51)
Example:
10 is the sum of the 10 digit-run which starts with 10:
[1,0,1,1,1,2,2,0,1,1]
11 is the sum of the 11 digit-run which starts with 11:
[1,1,1,2,2,0,1,1,0,1,1]
12 is the sum of the 12 digit-run which starts with 12:
[1,2,2,0,1,1,0,1,1,1,1,1]
20 is the sum of the 20 digit-run which starts with 20:
[2,0,1,1,0,1,1,1,1,1,2,1,3,2,1,1,0,0,1,0]
etc. In extending R, always try to use the smallest available integer not present in R and not leading to a contradiction.
Best,
É.
