Good sequencings of partial Steiner systems
A partial $(n,k,t)_\lambda$-Steiner system is a pair $(X,\mathcal{B})$ where $X$ is an $n$-set of vertices and $\mathcal{B}$ is a collection of $k$-subsets of $X$ called blocks such that each $t$-set of vertices is a subset of at most $\lambda$ blocks. An $\ell$-good sequencing of such a system is a labelling …
