• a(n) is the largest number which can be formed with no zeros, using least number of digits and having digit sum = n.at n=47A061219
• a(n) is the largest base-10 string such that the n-th number coprime to 10 does not divide any substring of a(n).at n=1A114922
• Numbers k such that k concatenated with itself gives the product of two numbers which differ by 8.at n=13A116161
• n times n+9 gives the concatenation of two numbers m and m-8.at n=10A116240
• Numbers k such that k * (k + 8) is the concatenation of a number m with itself.at n=13A116292
• a(n) = 10^n minus its binary weight.at n=6A218451
• For a positive number k, let L(k) denote the list consisting of k followed by the prime factors of k, with repetition, in nondecreasing order; sequence gives composite k such that the digits of L(k) are in nonincreasing order.at n=40A372034
