- Consider numbers m,n such that UnitaryPhi(m)=UnitaryPhi(n)=3*(m*n)^(1/2)/4, m <= n; sequence gives values of n.at n=9A143649
- Numbers m,n such that UnitaryPhi(n)=UnitaryPhi(m)=3/4*(m*n)^(1/2), m<=n; sequence gives values of m.at n=9A143650
- a(n) = (A002703(n)+2)/2.at n=25A262569
- Aliquot-like sequence based on the largest aliquot divisor of the sum of divisors of n (A371418) that starts with 222.at n=42A371423
