  Landau function $g(n)$ is the maximal possible least common multiple of
several positive integers with sum not exceeding $n$. Under additional
assumptions that these numbers are the differences of disjoint bi-infinite
arithmetic progressions the maximum is denoted $\tilde{g}(n)$, it was
introduced by Okhotin. We find a sharp logarithmic asymptotics of
$\tilde{g}(n)$.
