%N a(n) = A019565(n-th prime).
%e The 5th prime is 11 (decimal), which is 1011 in binary. So a(5) is the product of the primes corresponding to the 1's of 1011, 2*3*7 = 42.
%t Table[m = 1; o = 1; k1 = Prime[k]; While[k1 > 0, k2 = Mod[k1, 2]; If[k2 == 1, m = m*Prime[o]]; k1 = (k1 - k2)/2; o = o + 1]; m, {k, 1, 55}] (* _Stefan Steinerberger_, Mar 19 2006 *)
