Let $Ω$ be the set of odd positive integers and let $S:Ω\rightarrow Ω$ be the Syracuse function. It is proved that, for every permutation $σ$ of $(1,2,3)$, the set of triples of the form $(m,S(m),S^2(m))$ with permutation pattern $σ$ has positive density, and these densities are computed. However, there exist permutations $τ$ of $(1,2,3,4)$ such that no quadruple $(m,S(m), S^2(m), S^3(m))$ has permutation pattern $τ$. This implies the nonexistence of certain permutation patterns of $n$-tuples $(m,S(m),\ldots, S^{n-1}(m))$ for all $n \geq 4$.
