• T(2n-1,n-2), T given by A026568.at n=8A026578
• a(n) = T(2*n-1, n-2), where T is given by A026584.at n=8A026594
• Numbers k for which phi(A267099(k)) is equal to phi(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 phi is Euler totient function.at n=5A354194
