Number of compositions of n into 7 ordered relatively prime parts. A23032

Square array A(n,k), n>=0, k>=0, read by antidiagonals, where column k is the expansion of e.g.f. 1/(1 + k - ∑_j=1..k exp(j·x)). A320253

For a rational number p/q let f(p/q) = p·q divided by the sum of digits of p and q; a(n) is obtained by iterating f, starting at n/1, until an integer is reached, or if no integer is ever reached then a(n) = 0. A59175
