COMMENTS

Start with decimal expansion of pi: 3,1,4,1,5,9,2,6,5,3,5,8,9,7,9,3,2,3,8,4,6,2,6,4,3... Part the sequence to the sections with distinct digits: s={3,1,4},{1,5,9,2,6},{5,3},{5,8,9,7},{9,3,2},{3,8,4,6,2},{6,4,3},... Then A104807(n) = length[s(n)]: 3,5,2,4,3,5,3,... Sections with maximal length=10 A104808
