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 — planning for improvement of Commutative property before heading to the GAR.
4 — Geometric series
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 — blank
7 — Equilateral triangle
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

Aftermath

Potential FA

Potential FL

Potential GA

Deltahedron — thinking about adding [1] and (non-convex) deltahedral graph [2] [3], after which put it to GOCE (maybe not so needed anyway, but for real?)
Pentagonal bipyramid — Thinking for some expansion

Others

Bilunabirotunda — thinking about its construction by tridiminished icosahedron and wedge [4]
Cube — expanding the topics: unit-sided cube as a canonical unit and cubical grids as the most common coordinate system.
Composite polyhedron — still new, awaiting more published sources before expand
Equilateral triangle — sourcing and expanding
Geometric series — probably more rewriting and verifiablity about the sources
Gyroelongated square bipyramid —
Pentagonal gyrobicupola — JSTOR 27301198
Regular icosahedron — more sourcing and more expansion of the article.
Triangle — sources problem
Triangular cupola — explaining to determine the height and volume
Truncated dodecahedron — some expansion would be needed. I'm surprised this was a failed FAC.
