 OFFSET 1,2 COMMENTS The subsequence of number of initial digits of ternary Pi wherein the digit counts of zeros, ones, and twos are all exactly equal begins 0, 15, 18. The next term, if it exists, is > 3^21 > 10^10. LINKS Hans Havermann, Table of n, a(n) for n = 1..1194 EXAMPLE Ternary Pi is 10.01021101222201021100211... 0 is in the sequence because the first 0 digits contain 0 zeros and 0 ones. 22 is in the sequence because the first 22 digits contain 8 zeros and 8 ones. 23 is in the sequence because the first 23 digits contain 8 zeros and 8 ones.
