a(n) = (5·10ⁿ - 41)/9 for n > 0. A173804

Numbers such that each decimal digit d (for all d in the range 1 <= d <= 9) occurs only in runs of length exactly d. A140057

For k in {2,3,...,9} define a sequence as follows: a(0)=0; for n>=0, a(n+1)=a(n)+1, unless a(n) ends in k, in which case a(n+1) is obtained by replacing the last digit of a(n) with the digit(s) of k². This is k(7). A237344
