• Third column of A071223.at n=24A087645
• 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.at n=25A108224
• Ternary emirpimes.at n=20A119684
• X values of the complete set of 23 integer solutions to the Ochoa curve equation.at n=21A141144
• Integers whose decimal representation consists of three distinct digits, one appearing once, one appearing twice, and one appearing three times.at n=24A182040
• Write A003511(n) in the base {1, 3, 4, 11, 15, 41, 56, 153, 209, ...} (see A002530).at n=34A276386
• "Inside numbers". Pick a term "t" and one of its digits "d". Now jump to the right over d digits if "d" is odd, and to the left over d digits if "d" is even. Whatever the "d" you choose, you will stay on "t".at n=44A284515
• Semiprimes with sum of digits 4.at n=17A382073
