OEIS Sequences

Convolution of sequence of primes with sequence σ(n). A86718

Expansion of ∏_k>=1 (1+x^k)^k / (1-x^k). A262667

Nearest integer to the space diagonal of the smallest (measured by the longest edge) primitive (gcd(a,b,c)=1) Euler bricks (a, b, c, sqrt(a² + b²), sqrt(b² + c²), sqrt(a² + c²) are integers). If the space diagonal is an integer then the Euler brick is called a "perfect cuboid". There are no known perfect cuboids. A141029
