%N a(1) = 1; then distinct numbers such that both the product of two successive terms + 1 and the ratio of the larger to the smaller of two successive terms + 1 is a prime.
%C a(k+1) is either a multiple or a divisor of a(k).
%e 8 follows 2 as both 2*8 + 1 = 17 and 8/2 + 1 = 5 are primes.
%Y Cf. A084040, A084041.
