• Largest n-digit number with exactly n divisors, or 0 if no such number exists.at n=5A070845
• a(n) = the largest n-digit number with exactly 6 divisors, a(n) = 0 if no such number exists.at n=5A182672
• a(n) is the last term of the analogous sequence to A121805, but with initial term n, or -1 if that sequence is infinite.at n=18A330129
• a(n) is the least term of the first run of A331786(n) consecutive numbers whose sum of digits (A007953) is not divisible by n.at n=9A352688
• Numbers without comma-successors: these are the numbers k such that if the commas sequence A121805 is started at k instead of 1, there is no second term.at n=39A367341
