OEIS Sequences

Sum of the first n primes. A7504

Number of 7's in all partitions of n. A24791

a(n) = n·prime(n) - ∑_i=1..n prime(i). A152535

A051838 gives numbers m such that the sum of first m primes divides the product of the first m primes. This sequence gives corresponding values of the sum of first m primes. A140763

a(n) = ∑_{k=0..floor(n/2)} T(n-k,k), T given by A026747. A26757

Triangle read by rows: T(n,k) is the number of permutations of {1,2,...,n} having k up-down runs (1 <= k <= n). A186370

Compound filter: a(n) = P(A001511(n), A161942(n)), where P(n,k) is sequence A000027 used as a pairing function. A286260

a(1) = 0; a(n) = smallest composite number which is a sum of n distinct primes. A73619

Right-truncatable semiprimes. A85733
