Article: Symmetry groups are groups consisting of symmetries of given mathematical objectsbe they of geometric nature, such as the introductory symmetry group of the square, or of algebraic nature, such as polynomial equations and their solutions. Conceptually, group theory can be thought of as the study of symmetry.t["] Symmetries in mathematics greatly simplify the study of geometrical or analytical objects. A group is said to act on another mathematical object X if every group element performs some operation on X compatibly to the group law. In the rightmost example below, an element of order 7 of the (2,3,7) triangle group acts on the tiling by permuting the highlighted warped triangles (and the other ones, too). By a group action, the group pattern is connected to the structure of the object being acted on.

Question: What term describes the introductory symmetry group of the square?
Ans: geometric nature

The problem: Answer a question about this article:
In the Roman era, copper was principally mined on Cyprus, the origin of the name of the metal from aes yprium (metal of Cyprus), later corrupted to uprum, from which the words copper (English), cuivre (French), Koper (Dutch) and Kupfer (German) are all derived. Its compounds are commonly encountered as copper(II) salts, which often impart blue or green colors to minerals such as azurite, malachite and turquoise and have been widely used historically as pigments. Architectural structures built with copper corrode to give green verdigris (or patina). Decorative art prominently features copper, both by itself and in the form of pigments.
What is the name of the color pigment on building structures that are made using copper.
****
The answer: green verdigris

Problem: Please answer a question about the following article about Nintendo Entertainment System:
In the longer run, however, with the NES near its end of its life many third-party publishers such as Electronic Arts supported upstart competing consoles with less strict licensing terms such as the Sega Genesis and then the PlayStation, which eroded and then took over Nintendo's dominance in the home console market, respectively. Consoles from Nintendo's rivals in the post-SNES era had always enjoyed much stronger third-party support than Nintendo, which relied more heavily on first-party games.
With the NES at its end, which competing consoles with less strict licensing terms were supported?
A: Sega Genesis and then the PlayStation

Question: Read this and answer the question

Constantine the Great, who along with Licinius had decreed toleration of Christianity in the Roman Empire by what is commonly called the "Edict of Milan", and was the first Roman Emperor baptized, set precedents for later policy. By Roman law the Emperor was Pontifex Maximus, the high priest of the College of Pontiffs (Collegium Pontificum) of all recognized religions in ancient Rome. To put an end to the doctrinal debate initiated by Arius, Constantine called the first of what would afterwards be called the ecumenical councils and then enforced orthodoxy by Imperial authority.

What did Constantine the Great and Licinius pass to introduce toleration of Christianity in the Roman Empire?
Answer: Edict of Milan

Over the years, various attempts have been made to synthesize a single Buddhist text that can encompass all of the major principles of Buddhism. In the Theravada tradition, condensed 'study texts' were created that combined popular or influential scriptures into single volumes that could be studied by novice monks. Later in Sri Lanka, the Dhammapada was championed as a unifying scripture.
There have been attempts to create a single text with all the main ideas of what religion?
Buddhism
