Appears in sequences

• Numbers in which each digit is the (immediate) successor of the previous one (if it exists) and 0 is considered the successor of 9.at n=47A059043
• Triangle read by rows in which the n-th row contains the n numbers in increasing order formed by the concatenation of first n-1 numbers. (The digits of the numbers with 2 or more digits are taken as one entity.) First row is taken to be 0.at n=27A081539
• a(1) = 1; for n > 1, a(n) > a(n-1) is the smallest number such that the concatenation a(1)a(2)a(3)... forms a cyclic concatenation of 123456789 (of nonzero digits).at n=21A081549
• Numbers k with increasing digits such that the digits of k appear among the digits of the k-th prime number.at n=2A103174
• Numbers with digits in ascending order that differ exactly by 1.at n=36A138141
• a(n) is the smallest number not yet in the sequence such that the concatenation of all terms yields a periodic stream of digits 1, 2, 3, ..., 7 (repeat from 1).at n=41A165305
• Triangle T(n,k) read by rows: Substring of k digits of sequence A007376, ending at position n, 1 <= k <= n.at n=26A224841
• Concatenation of the numbers from 2 to n.at n=5A262571
• Square array A(m,n) = concatenation of { m, m+1, ..., m+n }, with m, n >= 1, read by falling antidiagonals.at n=16A285807
• Lexicographically first sequence of distinct terms such that any set of six successive digits can be reordered as {d, d+1, d+2, d+3, d+4, d+5}, d being the smallest of the six digits.at n=65A302501
• Lexicographically first sequence of distinct terms such that any set of seven successive digits can be reordered as {d, d+1, d+2, d+3, d+4, d+5, d+6}, d being the smallest of the seven digits.at n=48A302502
• Lexicographically first sequence of distinct terms such that any set of eight successive digits can be reordered as {d, d+1, d+2, d+3, d+4, d+5, d+6, d+7}, d being the smallest of the eight digits.at n=31A302503
• Lexicographically earliest sequence of distinct positive numbers such that if we add eight successive digits the result is divisible by 8.at n=26A327733
• Lexicographically earliest sequence of distinct positive numbers such that if we add ten successive digits the result is divisible by 10.at n=47A327735
• Numbers whose digits are nonzero, consecutive, and all increasing or all decreasing.at n=62A352927
