Series reversion of x*(1-x-2·x²)/(1-x). A235349

Row sums of A373424. A373353

a(n) is the largest number such that all of a(n)'s length-n substrings are distinct and divisible by 59. A93259

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

a(n) = lcm{1, 2, ..., n}/(n*(n-1)), n >= 2. A99946
