On the Existence of Skew Room Frames of Type $t^u$

Abstract

It is shown that if $t>1$ and $u\ge 5$, then the known necessary condition for the existence of a skew Room frame of type $t^u$, is also sufficient with the possible exception of $(u,f)$ where $u=5$ and $t\in \{11,13,17,19,23,29,31,41,43\}$.
