OEIS Sequences

Numbers n such that prime(n) == -1 (mod n). A45924

Number T(n,k) of permutations p of [n] such that 0p has a nonincreasing jump sequence beginning with k; triangle T(n,k), n>=0, 0<=k<=n, read by rows. A291684

a(1) = 8; a(n) is smallest number > a(n-1) such that the juxtaposition a(1)a(2)...a(n) is a prime. A74344

Table T(n,k), n>=0, k>=0, read by antidiagonals, where the e.g.f. for column k satisfies A_k(x) = exp(x·A_k(((x+1)^k-1)/k)) if k>0 and A₀(x) = exp(x·A₀(0)) = exp(x). A143632

Values of transition of A072608(n) from alternating behavior (0,1,0,1,..) into steadily-1 (1,1,1,..) behavior or changing back. Expressing in terms of A072609(n): at n values it switches from steadily 0 into steadily 1 successive values or back. A72610

a(n) = sum of lengths of strings that can be generated by any starting string of n 2's and 3's that starts with a 2, using the rule described in the Comments lines. A93369

Number of doubletons in all partitions of n. By a doubleton in a partition we mean an occurrence of a part exactly twice (the partition [4,(3,3),2,2,2,(1,1)] has two doubletons, shown between parentheses). A116646

Number of partitions of n² into squares not less than n. A93116

Smallest k such that in the interval [1,k] in A242033 all odd primes <= prime(n) are present. A242036

Denominators of continued fraction convergents to sqrt(790). A42523
