• Integer areas A of the integer-sided triangles such that the inradius and the radius of the three excircles are perfect squares.at n=19A233317
• Numbers which have identical primes in n and d(n) but are not refactorable.at n=13A235525
• LB numbers: positive integers of the form m = a*10^k+b (with a > 0 and b < 10^k) satisfying two properties: 1) the set of prime factors of m is the union of the sets of prime factors of a and b; and 2) A001222(m) = A001222(a) + A001222(b).at n=36A267856
