``Is following theorem known?'' by MakotoKohno on 2007-06-22 08:47:38
Let $ S$ be the set of odd positive integers.

We define $R:S \longrightarrow \ S $ such that $R(n) = (3n+1)/2^r$, with $ r$ as large as possible.

Next we define $ M(n)=sup(n,R(n),R(Rn)),...}$ for every odd positive integer.

Then

THEOREM
 Let $ K$ be a positive number.
 Then there exist odd integer $ n$ such that $ M(n)/n > K$ .
