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... Split the sequence into maximal 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 a(n) = length[s(n)]: 3,5,2,4,3,5,3,... Sections with maximal length = 10 A104808.
