Example 10.2.3.6. Let $X_{\bullet }$ be a simplicial set and let $n$ be an integer. Then $X_{\bullet }$ is $n$-skeletal (in the sense of Definition 10.2.3.4) if and only if it has dimension $\leq n$ (in the sense of Definition 1.1.3.1) . This is a reformulation of Proposition 1.1.3.11 (see Remark 1.1.3.12).
