 OFFSET 0,1 COMMENTS a(m)=c means that c + digit_length(m) - 1 is the minimal number of decimal digits of Pi after the decimal point containing all m+1 digit strings 0, 1, 2, ..., m in increasing order from left-to-right (with intervening digit strings of course) - but with some strings overlapping if m >= 34. a(10)=163 ==> 163+2-1=164 digits are necessary to contain in the 11 strings 0, 1, 2, ..., 10 in order. LINKS Table of n, a(n) for n=0..48. Dave Andersen, Pi-Search Page Eric Weisstein's World of Mathematics, Pi Digits. EXAMPLE a(0) = 32, the position of the first 0 in the decimal expansion of Pi. a(1) = 37, the position of the first 1 after the first 0. a(33) = 1667, the starting position of the first string 33 such that a(33) > a(32)=1501. a(34) = 1668, the starting position of the first string 34 such that a(34) > a(33)=1667. Note that these occurrences of 33 and 34 overlap. CROSSREFS Cf. A014777 (position of first n).
