• a(n) = Sum_{ k, k|n } 2^(k-1).at n=31A034729
• Partitions encoded by interleaving bits in parts. The partition [P1+P2+P3+...] with P1>=P2>=P3>=... is encoded in binary by recursively interleaving the bits of P1 with the (recursively interleaved bits of P2 with the (recursively...)).at n=29A059902
• a(0) = 0, a(n) = Sum_{i=0..n-1} 2^((2^i)-1).at n=6A072639
• Multiplies by 2 and shifts right under the XOR BINOMIAL transform (A099901).at n=31A099902
• a(2n) = 2^(2n), a(2n+1) = 2^(2n+1) + a(n).at n=31A127804
