Let $L$ be a quasidiscrete linear ordering. We specify some conditions for the existence of a computable presentation for $L$ or for the structure $(L,\operatorname{adj})$, where $\operatorname{adj}(x,y)$ is a predicate distinguishing adjacent elements.
Keywords: computability, quasidiscrete linear ordering.
