Abstract: In this paper, we present a particularly simple and direct proof that the set of noncontact-sufficient ( $ \mathcal{K}$-sufficient) germs are of infinite codimension. Our proof gives, for each $ k$, an integer $ r$ with the property that almost all $ r$-jets over any $ k$-jet $ z$ is $ \mathcal{K}$-sufficient. Similar results are obtained for $ \mathcal{A}$ or right-left equivalence when the source and target dimensions $ (n,p)$ are (2,2) and (2,3).
