List of totally balanced sequences of 2n binary digits written in base 10. Binary expansion of each term contains n 0's and n 1's and reading from left to right (the most significant to the least significant bit), the number of 0's never exceeds the number of 1's. A14486

a(n) = prime(n) - 1. A6093

Positive integers congruent to 2 (mod 4): a(n) = 4·n+2, for n >= 0. A16825

The primes doubled; even semiprimes. A100484

Finitary numbers. Matula-Goebel numbers of rooted identity trees. A276625

Digitally balanced numbers: positive numbers that in base 2 have the same number of 0's as 1's. A31443
