• Number of length n arrays of permutations of 0..n-1 with each element moved by -n to n places and the total absolute value of displacements not greater than n.at n=14A263932
• Number of length n arrays of permutations of 0..n-1 with each element moved by -7 to 7 places and the total absolute value of displacements not greater than n.at n=14A263938
• 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=20A354194
