• a(n) is the last defined element in the sequence n, f(n), f(f(n)), ..., where f(t) = lcm(t,(b+c)/2) with b < c smallest consecutive divisors of t with c - b > 1 and f(t) is undefined if such b, c do not exist or b + c is odd.at n=28A206034
• Noncubefree numbers k such that A073185(k) > 2*k.at n=28A357700
• Let D(k) = {d(k,i)}, i = 1,2,...,q be the set of q divisors of an integer k. a(n) is the smallest number k such that there exist exactly n distinct integers M, 1 < M <= k, where each set D(k) mod M = {0,1,2,...,M-1}.at n=34A379647
