I ran across this blog, https://dicemaniacsclub.wordpress.com/, recently; they have a Facebook group: https://www.facebook.com/DiceManiacsClub/. In the past, I had a lot more dice than I have right now. In the past, I had several 100 sided dice (D100, officially known as Zocchihedron https://en.wikipedia.org/wiki/Zocchihedron; unofficial nickname: golf ball – it’s not as obvious in the Wikipedia image, but if you have seen one in person, you would unde, not sure rstand why they are called golf balls). Here are some YouTube videos: https://www.youtube.com/watch?v=zmB2If4AvG0; Gamescience YouTube channel: https://www.youtube.com/channel/UCcXcByPbEDCTI5Ic_d2FfPA/videos. which includes some videos of Lou Zochhi – more about Lou at https://en.wikipedia.org/wiki/Lou_Zocchi. I also had several D30s which is close to the same size of the D100. At the time, the Zocchihedron (D100) was the largest number of sides dice had. Later, somebody created a D120 which is supposed to be the most sides that can be created mathematically although the Dice Collector (see the link below) has a D1000 in his collection, not sure if it’s a D10 numbered 100 – 000 or an actual D1000: https://www.mathartfun.com/thedicelab.com/d120.html.
d120 and d48
One-hundred-twenty-sided and Forty-eight-sided Dice
The d120 is the ultimate fair die allowed by Mother Nature (i.e., mathematics)! The d120 is based on a polyhedron known as the disdyakis triacontahedron. The d48 is based on a polyhedron known as the disdyakis dodecahedron. For both dice, each face is an elongated triangle. These dice are perfectly numerically balanced, with the same sums for numbers around vertices of the same type. The dice are available in white, black, red, blue, green and purple. They are available at The Dice Shop at Mathartfun.com. Click here to learn more about the design.
The d120 can be used as a dn, where n is any proper factor of 120, including all of the dice in a standard seven-dice polyset. Click here for more information.
Click here for a pdf with tables for using the d48 as a d3, d4, d6, d8, d12, d16, or d24.
I have never owned a D120 or most of the other sided dice mentioned by the Dice Collector who owns the record for largest dice collection: http://dicecollector.com/. Here’s his dice collection by number of sides: http://www.dicecollector.com/DICEINFO_COLLECTION_STATISTICS_BY_SIDES.html. At my largest, I owned maybe a couple hundred dice: mostly D4, D6, D8, D10, D12, D20, D30, D00 (different than D100 as they were D10s numbered 10 through 00), and D100.
While most of the dice are designed for gaming (RPGs, wargaming, board games, etc.), you can use them for other things. A few specialty dice can be used for writing as they have words on them instead of numbers. You could use dice with any of the numerous random tables available on DriveThru RPG (DTRPG) to generate plot points, names, etc.
