OEIS Sequences

Let u be any string of n digits from {0,...,3}; let f(u) = number of distinct primes, not beginning with 0, formed by permuting the digits of u to a base-4 number; then a(n) = max_u f(u). A65845

a(n) = A063997(n)/4. A88406

a(n) = n³ + (n+1)³ + (n+2)³ + (n+3)³ + (n+4)³. A27604

a(n) = (2·n+1)*(7·n+1). A33572

a(n) = floor((-1)ⁿ*n!*(E(n,2)-E(n,1)*E(n-1,1))) where E(n,x) = ∑_k=0..n (-1)^k*x^k/k!. A65955

Primitive terms of A389634. A389635

Odd 9-gonal (or enneagonal) numbers. A28991

a(n) = round(126*φⁿ). A80074

Enneagonal numbers for which the product of the digits is also an enneagonal number. A117052

Base 6 digits are, in order, the first n terms of the periodic sequence with initial period 3,1,2,0. A37781
