Appears in sequences

• a(n) = 5*(10^n - 1)/9.at n=8A002279
• Repdigital lucky numbers.at n=14A031882
• a(n) = floor(10^9/n).at n=17A033423
• a(0) = 1; a(n) is obtained by incrementing each digit of a(n-1) by 2.at n=17A061512
• a(1) = 10, a(n)= number obtained by adding to each digit of a(n-1) the next digit and adding the leading digit to the final digit.at n=8A061590
• Least concatenation of n to have exactly n prime factors with multiplicity.at n=4A118133
• The smallest number that has more copies of some digit than all previous terms of the sequence put together.at n=32A179310
• Value of decimal number corresponding to the string of equal digits starting at position A277259(n) after the decimal point in the decimal expansion of the Golden ratio (phi).at n=7A277260
• Absolute lucky numbers: every permutation of digits is a lucky number.at n=26A309406
• Expansion of x*(1 + 5*x + 40*x^2)/((1 - x^2)*(1 - 10*x^2)).at n=16A322927
• Numbers k such that the infinite sequence of digits consisting of the final digit of k^m for m = 2, 3, 4, ... is the same as the sequence of digits obtained by concatenating infinitely many copies of k.at n=36A344555
• Numbers m with decimal expansion (d_1, ..., d_k) such that d_i = m ^ i mod 10 for i = 1..k.at n=39A344823
