Abstract
We determine which non-crystallographic, almost-crystallographic groups of dimension-4 have the R∞-property. We then calculate the Reidemeister spectra of the 3-dimensional almost-crystallographic groups and the 4-dimensional almost-Bieberbach groups.

低维准晶群的 Reidemeister 谱
摘要
我们确定哪些非晶体的、几乎晶体的维数 4 组具有R ∞ -性质。然后我们计算 3 维几乎结晶群和 4 维几乎比伯巴赫群的 Reidemeister 光谱。
