Appears in sequences

• Convolution of sequence of primes with sequence sigma(n).at n=31A086718
• 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(a^2 + b^2), sqrt(b^2 + c^2), sqrt(a^2 + c^2) are integers). If the space diagonal is an integer then the Euler brick is called a "perfect cuboid". There are no known perfect cuboids.at n=30A141029
• Expansion of Product_{k>=1} (1+x^k)^k / (1-x^k).at n=16A262667
• a(n) = Sum_{d|n} (n/d)^(d-1) * binomial(d+n/d-1,d).at n=20A360948
