EXAMPLE
At k=3, we have
r(r(r(r(r(r(r(3)+1)+1)+1)+1)+1)+1)+1
= r(r(r(r(r(r(4+1)+1)+1)+1)+1)+1)+1
= r(r(r(r(r(r(5)+1)+1)+1)+1)+1)+1
= r(r(r(r(r(8+1)+1)+1)+1)+1)+1
= r(r(r(r(r(9)+1)+1)+1)+1)+1
= r(r(r(r(14+1)+1)+1)+1)+1
= r(r(r(r(15)+1)+1)+1)+1
= r(r(r(22+1)+1)+1)+1
= r(r(r(23)+1)+1)+1
= r(r(33+1)+1)+1
= r(r(34)+1)+1
= r(48+1)+1
= r(49)+1
= 66+1
= 67.
