• Concatenations of cyclic permutations of initial positive integers.at n=16A001292
• Numbers with 6 distinct digits {1,2,3,4,5,6} such that all adjacent digits (as well as first and last digits) are coprime.at n=6A104973
• Integers are written in the form abcd...n where "a" means "At position a in this integer there is a digit b"; "b" means: "at position b there is a digit c"; "c" means: "at position c there is a digit d"; ... and "n" means: "at position n there is a digit a".at n=29A105956
• a(n) is the smallest number not already in the sequence, such that the concatenation of all a(n) displays the periodic digit string 1, 2, 3, 4, 5, 6 (and repeat).at n=32A165304
• 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=64A302501
