This is not a sandbox. I deliberately create it with some objective, i.e., a list of the sandboxes, which I will probably utilize for testing, and practicing writing (or expanding) an article.

List

1 — Fundamental theorem of calculus
2 — Continuation of Tetrahedron
3 — Favorite images I have uploaded
4 — blank
5 — Additional WP:3TOPE features: some tests of tables inspired from the WP:ELEMENT but with horrible feature, some book cover tests for providing class of polyhedrons in the project.
6 — List of unsolved problems in polyhedra
7 — Rewriting Exponentiation
8 — List of uncreated polyhedral articles
9 — List of GA and FA, summarizing the whole category of GA-class in the form of WP:GA/M and FA-class in the form of FA
10 — List of high-class nomination and review
11 — blank
12 — some notes
13 — blank

Aftermath

Augmented pentagonal prism — doi.org/10.1080/00958972.2018.1442003
Deltahedron — thinking about adding and (non-convex) deltahedral graph , after which put it to GOCE (maybe not so needed anyway, but for real?)
Dirac delta function — unsourced
Elongated triangular pyramid
Equilateral triangle — sourcing and expanding
Geometric series — probably more rewriting and verifiability about the sources
Gyrobifastigium — application in chemistry
Gyroelongated square bipyramid —
Hilbert space — unsourced
Pentagonal gyrobicupola — JSTOR 27301198,
Polar coordinate system —
Polyhedron — sourcing and expanding. Lots of conflict.
Regular dodecahedron — spherical dodecahedron and sourcing problem
Regular polytope — sourcing problem
Representation theory of the Lorentz group — unsourced
Square antiprism —
Snub disphenoid —
Taylor series — unsourced
Triangle — sourcing problem
Triangular cupola — explaining to determine the height and volume
Triangular orthobicupola — coordination chemistry , closed-packed structure , ,
Triangular prism (applications: 10.1017/jfm.2025.10781)
Truncated dodecahedron — some expansion would be needed. Surprisingly, it was a failed FAC.
