Point group
In geometry, a point group is a mathematical group of symmetry operations (isometries in a Euclidean space) that have a fixed point in common. List of point groups One dimension There are only two one-dimensional point groups, the identity group and the reflection group. wikipedia.org

Point Group of a pattern I need to determine the point group of the following patterns: !enter image description here I think the one on the left is $D_1$ and the one on the right is $D_2$
Symmetry and unit cell Then use the Wallpaper group diagram: ! Both of these latices have $D_2$ point groups at the center of the cell, as well as lower-order point groups at other points.

Connecting Point Group
The Connecting Point Group is a Late Neoproterozoic geological formation cropping out on the Avalon Peninsula of Newfoundland, dominated by deep marine Approximate age data from the middle of the group date it to ca. 610 Ma. It corresponds to the Conception Group and the St. wikipedia.org

Point group of a disjoint union of graphs Let $G$ be a graph. $\Gamma(G)$ is the point group og $G$, i.e. the automorphism group of $G$. Suppose $$G \cong nH $$ i.e. the disjoint union of $n$ graphs isomorphic to $H...
The point group $\Gamma(G)$ contains elements that map each copy of $H$ to itself. These two subgroups together generate a group called the wreath product $\Gamma(H) Wr S_n = \Gamma(H)^n \rtimes S_n$. Thus the graph $nH$ has $n!

The fundamental group of a point is $1$ > Show that the fundamental group of the point space $p$ is given as $\pi(p, w_0)=1$ where $w_0$ is the base point This is probably somewhat trivial, but I am looking for a pro...
Hence the fundamental group cannot have more than one element, so it is the trivial group.
