a(n) = ∑_{1 <= x₁, x₂, x₃ <= n} n/gcd(x₁, x₂, x₃, n). A372952

Number of (1,-1)-returns to the horizontal axis in all weighted lattice paths in L_n. The members of L_n are paths of weight n that start at (0,0) , end on the horizontal axis and whose steps are of the following four kinds: an (1,0)-step with weight 1, an (1,0)-step with weight 2, a (1,1)-step with weight 2, and a (1,-1)-step with weight 1. The weight of a path is the sum of the weights of its steps. A182897

a(n) is the smallest number such that a(n)*n is an anagram of a(n)*5. A175694
