%N Array read by upwards antidiagonals: a(n,k) = index of prime(k)^n in A098550.
%C Entry a(n,k), in row n and column k, is the index of the entry in A098550 such that A098550(a(n,k)) = prime(k)^n.
%C Conjecture: For all natural numbers i, j, k, prime(k)^i precedes prime(k)^(i+1) and prime(k)^j precedes prime(k+1)^j in A098550.
