• Binary encoding of quadratic residue set of n. L(1/n) is the most significant bit, L(n-1/n) is the least significant bit, i.e., the rows of A055088 interpreted as binary numbers.at n=22A055094
• Binary encoding of quadratic residue set formed for n-th prime, coerced to "complementarily symmetric binary sequence" with A080261 if the prime is of the form 4k+1.at n=7A080117
• Intersection of A080117 and A014486.at n=5A080118
• Binary encoding of quadratic residue set for each prime. a(n) = A055094(A000040(n)).at n=8A080146
