Both have keyword:more, but A049117 has a few more terms than A227946.

I tried out phi(14348907) = 9565938, the odd part of which is 4782969; then
phi(4782969) = 3188646, odd part of which is 1594323; phi(1594323) =
1062882... Then I realized 14348907 = 3^15 and obviously phi(3^n) = 2 *
3^(n - 1).

So unless there's a smaller number fitting the bill, 14348907 might be the
next term of A227946, assuming we decide to not recycle A227946.
