Number of lower triangles of a 4 X 4 0..n array with each element differing from all of its diagonal, vertical, antidiagonal and horizontal neighbors by one or less. A195234

Consider a decimal number of k>=2 digits z = d_k*10^k-1 + d_k-1*10^k-2 + ... + d₂*10 + d₁ and the sum y = ∑_x=2..k {∑_j=1..k-x{d_j+x-1*10^j-1} - ∑_j=1..x-1{d_j*10^j-1}}. Sequence lists the numbers for which y = τ(z), where τ(z) is the number of divisors of z. A248904
