WebThe 3.13 + 1 problem can also be formulated in the backwards direction, as that of determining the smallest set SO of integers containing 1 which is closed under the affine maps :r r—i 2:1: and 3:1: + 2 H 2:1: + 1, where the latter map may only be applied to inputs 3.1: + 2 whose output 2:1? + 1 will be an integer.
