COMMENTS

2 is nevertheless reached fairly soon, and after that the sequence proceeds exactly the same as A007542.

FORMULA
|
a(n+12) = A007542 (n) for n > 0. [Charles R Greathouse IV, Jan 24 2012]
a(n+1) = A203907(a(n)), a(1) = 3. [Reinhard Zumkeller, Jan 25 2012]

|
EXAMPLE
|
After 3, we have 3 * 55 = 165 because none of the other fractions give an integer. Then we can use 29/33, and thus 165 * 29/33 = 145, and so on and so forth.
