초록본문(Abstract) Negami found an upper bound on the stick number $s(K)$ of a nontrivial knot $K$ in terms of the minimal crossing number $c(K)$, which is $s(K) \leq 2c(K)$.
Huh, No and Oh proved that $s(L) \leq c(L)+2$ for all $2$-bridge knots and links $L$ with at least six crossings.
Let $K$ be a knot or link which admits a reduced Montesinos diagram having $c(K)$ crossings.
If each rational tangle of the diagram has five or more index of the related Conway notation, then $s(K)\leq c(K)+4$.
In particular, if $K$ is alternating, then $s(K)\leq c(K)+1$.
