Numbers k such that k concatenated with itself gives the product of two numbers which differ by 9. A116162
Fourth Lie-Betti number of a path graph on n vertices. A362007
a(n) is the largest number which can be formed with no zeros, using least number of digits and having digit sum = n. A61219
a(n) is the largest 5-digit number with exactly n divisors, or a(n) = 0 if no such number exists. A182698

Suppose you take the ten digits 0..9, arrange them in any order and then either concatenate adjacent ones or separate them with a plus or minus sign, e.g., 98-76+5-4-32+10 or 9-8-765+3041-2. The first expression totals to "1", the second example totals to "2275". This sequence lists the positive integers that cannot be expressed in this way. A108224
