COMMENTS

Presently identical to A050281, but it can be expected that the two will eventually differ, namely, as soon as a(n) > a(n+1) and A050281(n) = A050281(n+1).

a(10) > 2*10^9, according to the SubIdiom.com search engine. - M. F. Hasler, Apr 13 2019

EXAMPLE

Pi = 3.1415926... has a "run" of exactly one '2' in the 6th place after the decimal point, therefore a(1) = 6.
