OEIS Sequences

a(n) = ∑_d∣n d³*A000593(n/d). A288419

Numbers k for which φ(A267099(k)) is equal to φ(k), but the number of 4m+1 and 4m+3 primes in the prime factorization of k (when counted with multiplicity) is not equal. Here A267099 is fully multiplicative involution swapping the positions of 4m+1 and 4m+3 primes, and φ is Euler totient function. A354194

Let b(1)=1/n, b(2)=1, b(k+1)=abs(b(k))-b(k-1)²; then b(k) is >0 for k>a(n). A76635
