a(n) is the sum of the n-th row of the triangle formed by replacing each m in Pascal's triangle with σ(m). A74801

a(n) = (2^p+1)^p-1 modulo p², where p is prime(n). A260531

Low-temperature partition function expansion for hexagonal lattice (Potts model, q=3). A57385

a(n) = floor(10⁶/n). A33426

a(0) = 0; for n > 1, if a(n-1) has appeared three or more times then a(n) = total number of terms between the last and second-last appearance of a(n-1), minus the total number of terms between the second-last and third-last appearance of a(n-1). If a(n-1) has appeared two times, a(n) = total number of terms between the last and second-last appearance of a(n-1). If a(n-1) has appeared once, a(n) = 0. A328342
