OEIS Sequences

Numbers that are the sum of 10 positive 10th powers. A4810

Consider the recursion b(1,n) = 1, b(k+1,n) = b(k,n) + (b(k,n) reduced mod(k+n)); then there is a number y such that b(k,n)-b(k-1,n) is a constant (= A074482(n)) for k > y. Sequence gives values of y. A74483

Numbers n such that n and n+-1 have 4 distinct prime factors. A168628

Terms of A073872 that do not change their position in the rearrangement; i.e., values of A073872(n) which equal n(n+1)/2. A73873

Triangular numbers which are an average of four consecutive primes. A226196

a(n) = n * (n + 4) * (n + 8). A370914

E.g.f. A(x) satisfies A(x) = exp( arcsinh(x·A(x)) / A(x) ). A385428
