• Smallest number beginning with 1 that is the product of exactly n distinct primes.at n=9A106411
• Irregular triangle read by rows: T(n,k) (n >= 4, 4 <= k <= A384502(n)) is the smallest n-digit number m with k distinct prime factors, such that these factors can be divided into two subsets of at least two elements each, both summing to the same value. If no such number exists, T(n,k) = -1.at n=27A383858
• a(n) is the least number with exactly two distinct base-10 digits and exactly n distinct prime factors, or -1 if there is no such number.at n=8A386761
