• Floor[(80/81)*10^n].at n=7A057933
• a(n) = (10^n - 1)*(80/81) + n/9.at n=7A064617
• Let N = 123456789123456789123456789..., with the digits from 1 to 9 repeated indefinitely. Then a(n) is the n-digit number formed from the digits starting at the {n(n-1)/2 +1}-th position of N, read backwards if n is even.at n=7A066580
• a(n) = 12345679*n.at n=8A070189
• Smallest multiple of n which is a reverse concatenation of n nonnegative consecutive numbers, or 0 if no such multiple exists.at n=7A076803
• Smallest multiple of n which is the reverse concatenation of n consecutive numbers; or 0 if no such number exists.at n=7A083468
• Smallest multiple of n which is the concatenation of n successive numbers in descending order, or 0 if no such number exists.at n=7A087342

• Least k such that decimal representation of k*n contains only digits 0 and 8.at n=8A096687
• a(n)*n = A112907(n).at n=8A112908
• a(n) = 12345679 * A001651(n).at n=5A178069
