OEIS Sequences

Integers k such that k = Sum k/(p_i + j), where p_i are the prime factors of k (with multiplicity). Case j = -3. A380923

Triangle read by rows: T(n,k) = number of partitions of [1..k] into n nonempty clumps of sizes 1, 2, 3 or 4 (n >= 0, 0 <= k <= 4n). A144643

Partition number array, called M32(-5), related to A013988(n,m)= |S2(-5;n,m)| ( generalized Stirling triangle). A144268

Integers n such that for all i > n the largest prime factor of product(i+k, {k,0,15}) exceeds the largest prime factor of product(n+k, {k,0,15}). A209839
