Alright, I'll go first. Here's a recursive description of f'(n) = 3n+1 where n is in binary:
f 1 → 11 f 1ʸ → 101ʸ⁻²01 f 10ᵛ n → 110ᵛ⁻¹ (f n) f 1ʸ0 n → 101ʸ⁻²0 (f' n) f 1ʸ0ʷ n → 101ʸ⁻²010ʷ⁻² (f n) f' 1ᵛ → 01ᵛ⁻¹01 f' 1ᵛ0 n → 01ᵛ⁻¹0 (f' n) f' 1ᵛ0ʸ n → 01ᵛ⁻¹010ʸ⁻² (f n) y w > 1 v > 0

Notice how divide by two only removes redundant information (namely all leading zeros on the left of the binary string - little endian) therefore f' (corecursive with f(n) = 3n) is the only entropy-adding element of the collatz problem in binary
