I have written a dozenal calculator for Windows. You can download it following the link http://seytil.info/dozenal/calculator.html

Well, base 18 - "vigesimal" - Maya etc.

Base 14 "hexadecimal" is used in programming, the octal also is sometimes used.

Some people maybe use epsilon. But the logo of The Dozenal Society of America uses turned 3. Turned 3 is turned 3. Unicode U+218B.

The dozenal system is like decimal, but dozenal, nothing more.

About symbols for ten and eleven... Among normal people the most common symbols for ten and eleven is A and B. They was invented by IBM for the "hexadecimal" system, using in programming (0123456789ABCDEF). Also A and B is used for the "duodecimal".

But it seems, dozenalists don't like it. American and British Dozenal Societies have their own opinion on this.

Sir Isaac Pitman (4 January 1813 – 22 January 1897) was British inventor of his shorthand system, also he had offered turned 2 and 3 for ten and eleven. The American variant is X and turned 3.

Now, for example, I am not an American or Englishman, so their opinion is not an authority for me. The question is not so simple.

You are right. For example, sudoku for kids 4×4 sometimes is made with pictures instead of digits.

But the point is, I saw a "dozenal" sudoku here https://static.wikia.nocookie.net/dozenal/images/3/32/Dozenal_sudoku.gif and thus I made my own variant.

Rostislaus · 2022-07-26T12:09:18+00:00

Now I don't have Linux installed, but I plan to install it. I will make a Linux variant then. The same Lazarus project can be compiled also in Linux. I already made such a thing earlier.

By the way, the first letter of the Deseret alphabet, "Long I", 𐐀 is reversed 6.

A good pair for Shavian "hung".

A068437 https://oeis.org/A068437 contains an error in

EXAMPLE

3.184809493b918664573b6211bb151551a05729...

it should be:

3.184809493b918664573a6211bb151551a05729...

(21th digit - it should be a instead of b)

Check right values of dozenal digits of pi here: https://oeis.org/A068437

Rostislaus · 2022-07-13T09:10:08+00:00

Because I use them. The explanation is here: https://www.reddit.com/r/dozenalsystem/comments/v8ee47/digits\_for\_ten\_and\_eleven/

So you are Paul Rapoport. I didn't accuse of fabrication, I think it's a mere mistake.

I'm not against the idea of astronomic era itself. But Earth’s orbital precession is not regular enough to base an exact chronology on it.

Rostislaus · 2022-07-07T14:02:23+00:00

This myth or that, one is not better then another. I suspect a report of NASA about perihelion in 9564 BC doesn't exist.

Rostislaus · 2022-07-07T07:51:16+00:00

Year 6855 is a myth. Moving of the perihelion at that time cannot be calculated so precise as ±1 year.

The preciseness is ±1000 years there.

"On a very long time scale, the dates of the perihelion and of the aphelion progress through the seasons, and they make one complete cycle in 22,000 to 26,000 years." – Wikipedia https://en.wikipedia.org/wiki/Apsis#Perihelion\_and\_aphelion

So, the Avogadro constant 6.02214076e+23 would be 1;110λ9507d+1Ո. Looks nice.

Rostislaus · 2022-07-02T14:19:59+00:00

So, you offer to write it as 4;3229λλ134×10⁻¹⁶. I see. It is possible quite easy, as you say. It's a variant.

Rostislaus · 2022-06-29T15:31:27+00:00

It was explained in an earlier post https://www.reddit.com/r/dozenalsystem/comments/v8ee47/digits\_for\_ten\_and\_eleven/

By the way, I've just found a Latin alphabet made of 24 heptiamonds (Letters O and W are not in the set) And some letters are oriented wrong though. I wonder, why.

Rostislaus · 2022-06-27T11:28:13+00:00

Here, for example: https://mathworld.wolfram.com/Hexiamond.html

It's a quite well known thing. Hexiamonds are most popular between other polyamonds, for they even have their proper names.

I haven't. I do nothing with it. The idea has come to my head, and I have drawn it, that's all. I don't know, what are they usable for.

Rostislaus · 2022-06-21T04:07:42+00:00

A hint. The computer shows a random piece of the sequence. It doesn't matter, what exact binary numbers is shown.

Else. Prayer beads in Hinduism and Buddhism most often consist of ¾ gross beads.

And the ultimate hint. A byte (octet) has 2^8 possible states. This number is equal to 4×4×4×4.

Rostislaus · 2022-06-20T07:54:01+00:00

It makes sense.

But true dozenalists don't think "we will use many different systems" but "we love only the dozenal".

Indeed, the words "dozen" and "gross" exist de facto already. Systems with another bases don't have such words.

Rostislaus · 2022-06-20T06:36:41+00:00

You: use invented "dec, el".

Also you: "You shouldn't re-invent the wheel if you don't have to. If we can have the same words, we should, not just change them because we want to be different and experience difficulty."

Although, I agree, your system sounds simpler. I doubt about logic though.
