OEIS Sequences

Consider a non-palindromic number of k digits n = d_k*10^k-1 + d_k-1*10^k-2 + … + d₂*10 + d₁. Sequence lists the numbers n such that ∑_i=1..k-1{φ(∑_j=1..i{d_j*10^j-1})} = ∑_i=1..k-1{φ(∑_j=1..i{d_k-j+1*10^i-j})} (see example below). A241503

T(n,k)=Equals one maps: number of nXk binary arrays indicating the locations of corresponding elements equal to exactly one of their king-move neighbors in a random 0..2 nXk array. A220967

E.g.f.: 1/(cos(x) - sin(x)*cosh(x)). A205580

Equals one maps: number of nX2 binary arrays indicating the locations of corresponding elements equal to exactly one of their king-move neighbors in a random 0..2 nX2 array. A220964
