Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

%N Write down decimal expansion of Pi; starting with 31, divide up into chunks of minimal length so that chunks are increasing numbers and do not begin with 0.
%C Seems to grow slower than A016062 (another sequence built on the same principle, which begins with 3, 14, 15, 92, 653...).
%e a(4) = 265, the three digits of Pi following a(3) = 59, because neither 2 nor 26 is > 59. a(13) = 75105820 even though 7510582 > a(12), because a(14) may not begin with a 0.
%Y Cf. A000796, A037244, A035331.
