OEIS Sequences

Sum of the first n primes. A7504
Number of connected permutations of [1..n] (those not fixing [1..j] for 0 < j < n). Also called indecomposable permutations, or irreducible permutations. A3319
a(n) = 2·n2 - 2·n + 3. A97080
Triangle T(n,k) (1 <= k <= n) read by rows: T(n,k) is the number of permutations of [1..n] with k components. A59438
Square table, read by antidiagonals, where the g.f. for row n+1 is generated by: x·Rn+1(x) = (1+n·x - 1/Rn(x))/(n+1) with R0(x) = ∑n>=0 n!*xn. A111528
a(1) = 1; a(n) is smallest number >= a(n-1) such that the juxtaposition a(1)a(2)...a(n) is a prime. A33680
Triangular matrix T, read by rows, that satisfies: SHIFTLEFT(column 0 of Tp) = p*(column p+1 of T), or [Tp](m,0) = p·T(p+m,p+1) for all m>=1 and p>=-1. A104980
Trajectory of 40 under the map n-> A006369(n). A217729
Number of distinct integer partitions whose parts can be combined together using additions and multiplications to obtain n, with the exception that 1's can only be added and not multiplied with other parts. A319913
a(1) = 6; a(n) is smallest number > a(n-1) such that the juxtaposition a(1)a(2)...a(n) is a prime. A74342
