• a(1) = 2; for n>1, a(n) is the smallest integer > a(n-1) such that all primes <= a(n-1) divide at least one integer k for a(n-1) < k <= a(n).at n=17A113117
• a(1) = 2. a(n) is smallest integer > a(n-1) which is a multiple of the largest prime <= a(n-1).at n=17A113118
• a(1) = 1. If a(n) is composite, a(n+1) = 2*a(n)+1; otherwise, a(n+1) = 2*a(n).at n=16A125050
• Total number of parts coprime to n in the partitions of n into 10 parts.at n=49A363328
• Partition the natural numbers by letting a(1)=1 (denoting the set {1}) and for n>1 define a(n) to be the least integer such that the product of the set of integers {a(n-1)+1,...,a(n)} is an integer multiple of the previous partition's product.at n=17A381901
