Digits 3,1,4,... are indexed 1,2,3,... (in contrast to, e.g.,
A083600 -

If there are more than 6 equal digits starting at a(n), then a(n)+1 etc. is not listed, in contrast to, e.g.,
A083600 -
A083645, and most other sequences of this type. Therefore the sequence data yields only candidates for longer runs, but they cannot be deduced from the data as this sequence can be deduced from consecutive numbers in
A049517, cf. formula. -
