a(n) = 2ⁿ⁺²*(2ⁿ⁺¹-1). A59153

Nontrivial nonunitary multiply perfect numbers: the sum of the nonunitary divisors of n is a positive multiple of n; i.e., (σ(n) - usigma(n))/n is a positive integer. A64595

The number of length n binary words with some prefix which contains two more 1's than 0's or two more 0's than 1's. A233411
