Appears in sequences

• a(n) = A047848(7,n).at n=7A047855
• Leftmost 1 is converted to a 2, which then propagates one step at a time until it is rightmost; then it changes to a pair of 1's and the process repeats.at n=35A071762
• Largest multiple of n using only nonzero digits with digit sum n, or 0 if no such multiple exists.at n=7A075399
• Array in which the n-th row contains the multiples of n using nonzero digits and having a digit sum of n. Sequence contains the rows and a zero entry for rows with no terms (e.g. 10).at n=43A077755
• Largest multiple of n as a concatenation of its partitions.at n=7A079840
• a(1) = 1, then the smallest number not included earlier and not a string of 1's such that the concatenation a(n), a(n+1) is a palindrome.at n=23A083122
• Multiples of 8 in which there is no common digit in successive terms.at n=38A083496
• A Jacobsthal sequence (A078008) to base 4.at n=14A092900
• Erroneous version of A075399.at n=7A093425
• List of Lyndon words on {1,2} sorted first by length and then lexicographically.at n=23A102659
• Numbers k such that the concatenation of k with 8*k gives a square.at n=12A115549
• Smallest number whose sum of cubes of digits is n.at n=14A165370
• Table T(n,k) = ceiling(10^n/(10^k-1)), n >= 0, k >= 1, read by antidiagonals.at n=28A176088
• a(n) = A047848(n, n).at n=7A196793
• Smallest positive integer with n anagrams.at n=6A199357
• Numbers with digital product = 2.at n=21A199986
• Composite numbers whose product of digits is 2.at n=15A201015
• Good's example of a "Standard List" of prime words over the alphabet {1,2}.at n=23A212659
• Triangle read by rows: left edge is all 1's, right edge is 1, 2, 3, 4, ...; construct an internal entry by concatenating the two entries above it.at n=29A213057
• A base-3/2 sorted Fibonacci sequence that starts with a(0) = 0 and a(1) = 1. The terms are interpreted as numbers written in base 3/2. To get a(n+2), add a(n) and a(n+1), write the result in base 3/2 and sort the "digits" into increasing order, omitting all zeros.at n=15A305753
