Intrinsic linking and knotting in tournaments

A directed graph $G$ is $\textit{intrinsically linked}$ if every embedding of that graph contains a non-split link $L$, where each component of $L$ is a consistently oriented cycle in $G$. A $\textit{tournament}$ is a directed graph where each pair of vertices is connected by exactly one directed edge. We consider intrinsic linking and knotting in tournaments, and study the minimum number of vertices required for a tournament to have various intrinsic linking or knotting properties. We produce the following bounds: intrinsically linked ($n=8$), intrinsically knotted ($9 \leq n \leq 12$), intrinsically 3-linked ($10 \leq n \leq 23$), intrinsically 4-linked ($12 \leq n \leq 66$), intrinsically 5-linked ($15 \leq n \leq 154$), intrinsically $m$-linked ($3m \leq n \leq 8(2m-3)^2$), intrinsically linked with knotted components ($9 \leq n \leq 107$), and the disjoint linking property ($12 \leq n \leq 14$). We also introduce the $\textit{consistency gap}$, which measures the difference in the order of a graph required for intrinsic $n$-linking in tournaments versus undirected graphs. We conjecture the consistency gap to be non-decreasing in $n$, and provide an upper bound at each $n$.
