 A316915 For any k, the cumulative sum a(1) + a(2) + a(3) + ... + a(k) shares at least two digits with a(k). Lexicographic first sequence of positive integers without duplicate terms having this property. 5
 10, 100, 11, 13, 14, 16, 18, 20, 12, 23, 26, 29, 32, 35, 39, 24, 46, 51, 45, 40, 67, 74, 27, 19, 21, 90, 101, 30, 41, 106, 15, 61, 17, 31, 33, 37, 84, 50, 56, 62, 69, 47, 81, 91, 102, 60, 71, 92, 22, 28, 112, 34, 42, 25, 52, 117, 72, 82, 38, 95, 80, 103, 43, 73, 133, 36, 93, 53, 63, 70, 78, 83, 59, 49, 104 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,1 LINKS Jean-Marc Falcoz, Table of n, a(n) for n = 1..10001 EXAMPLE Here are the first terms of the sequence: 10,100,11,13,14,16,18,20,12,23,26,29,32,... and here are the cumulative sums: 10,110,121,134,148,162,180,200,212,235,261,290,322,... If we align a(n) and its cumulative sum, we see that at least two digits are shared:   10,100, 11, 13, 14, 16, 18, 20, 12, 23, 26, 29, 32,...   10,110,121,134,148,162,180,200,212,235,261,290,322,... CROSSREFS Cf. A316914 (where one digit is shared instead of two, by the cumulative sum).
