• The periodic part of the decimal expansion of 1/n. Any initial 0's are to be placed at end of cycle.at n=27A036275
• a(n) = periodic part of decimal expansion of n/n-th prime (leading 0's moved to end).at n=3A060251
• Periodic part of decimal expansion of 1/n (leading 0's omitted).at n=27A060284
• Numbers k divisible by exactly two nontrivial permutations (rearrangements) of the digits of k, excluding all permutations that result in digit loss.at n=0A090061
• Multiples of 142857.at n=3A101202
• Maximal term of TRIP-Stern sequence of level n corresponding to permutation triple (e,23,e).at n=39A271488
• a(n) = floor(((n mod 6)+1) * 10^floor((n/6)+1) / 7).at n=33A343915
• Array read by ascending antidiagonals: A(n,m) is obtained by concatenating the digits of floor(n/m) with those of its fractional part up to the digits of the first period, where the leading and trailing 0's are omitted.at n=51A382068
• Irregular table, read by rows, where row z = 2, 3, 4, ... lists pairs (y, x) such that x + y/z = concat(y, x)/z with 0 < y < z, gcd(y, z) = 1, and primitive x, cf. comments.at n=63A383188
