Given a finite poset P, a family F of elements in the Boolean lattice is induced-P-saturated if F contains no copy of P as an induced subposet but every proper superset of F contains a copy of P as an induced subposet. The minimum size of an induced-P-saturated family in the n-dimensional Boolean lattice, denoted sat * (n, P), was first studied by Ferrara et al. (2017).Our work focuses on strengthening lower bounds. For the 4point poset known as the diamond, we prove sat * (n, D 2 ) ≥ √ n, improving upon a logarithmic lower bound. For the antichain with k + 1 elements, we prove sat * (n, A k+1 ) ≥ (1 − o k (1)) kn log 2 k , improving upon a lower bound of 3n − 1 for k ≥ 3.
