OEIS Sequences

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(2n) = 2·a(2n-1), a(2n+1) = 2·a(2n)+1 (also a(n) is the n-th number without consecutive equal binary digits). A975

Numbers of the form 2^n-1*(2^n·m-1)/(2ⁿ-1), n >= 1, m >= 1. A272919
