Hi. My name is Dedhert.Jr. I am a Wikipedia editor contributing here by glossing articles to be suitably referenced articles; my contribution is mathematics, especially in polyhedral articles. Over the past months, I have gained many experiences from events or incidents, including how the tensions between users look, how to resolve a problem, and many more. Whenever I contribute here, some users may look at my horrendous action; whenever it does, giving a warning notification is sufficient to remind me how I behaved here (and I will try to fix it). See my edits and contributions for more information.

Some of my tools here, or general tools in Wikipedia:

• User:Dedhert.Jr/common.js (cannot install)
• Orphan link

• Cube
• List of Johnson solids
• Pentagonal pyramid
• Square pyramid
• Triangular bipyramid

• "... that square pyramids can have different shapes, and pyramidologists have put forward multiple theories on which of these shapes was used for the Egyptian pyramids?"

• 

  "... that there are 11 ways (pictured) to unfold a cube?"
