Re: Hexagonal 37
I noticed that the diagram above has some notations out of place when viewed in some browsers, due to slightly different widths relative to the tabs I used. If the above is messed up in your browser, the following should look better, and vice versa. D:x::\\!::\\!: 141 B:#::\\!::\!: F:x::\\!::\!: 955...

Re: Hexagonal 37
Hi cicada . Welcome to the Sagittal forum. I'm sorry it has taken me so long to respond to this. It was quite a puzzle. I could not find any online resources describing "Hegagonal37", it's purpose or structure. And now that I have analysed it enough to know how it should be notated I am my...

A mental algorithm for divisibility by integers from 2 to 13
Everyone knows how to mentally check the divisibility of three-digit-or-more decimal integers by 2, 5 or 10, and many people know how to check divisibility by 3 or 9. A year ago, Numberphile gave methods to check for divisibility by integers from 2 to 12. But these methods are so many and varied, it...

Re: 13 EDO
Every other note of 26edo is now the recommended Sagittal notation for 13edo. See 13 near the top left of the periodic table: https://sagittal.org/

Re: The Sagittal Xenharmonikôn article updated
I made a very minor correction to the Sagittal Xenharmonikôn article at https://sagittal.org/sagittal.pdf. In footnote 20 on page 25 I changed "130-EDO uses the entire 'Spartan' symbol set" to "130-EDO uses almost the entire 'Spartan' symbol set".

Re: Negri temperament
Sorry Herman. I somehow missed your previous post until now. The F:\!/: notation does seem simpler, at least in those few bars. But I'd hate for the decision to be forced on you by the lack of a symbol for +11g (175 ¢ when the generator is 125 ¢, i.e. in 48edo). The only suggestion I have for +11g i...

Re: Negri temperament
Good to hear from you, Herman. I agree those are valid, except I get -18g, not +11g, for :(|||~: . One different suggestion I have is to use :/|\: for +10g, based on extending the mapping of the 124 to 126 cent generator to ⟨ 0 -4 3 -2 14]. :/|\: is used in 48edo which supports Negri temperament. Th...

Re: James algebra provides a clever notation for elementary functions
A Unicode text version using brackets We don't always have access to MathJax or LaTeX. It would be good to still be able to write James algebra expressions in plain Unicode text in a way that can be mixed with traditional algebra. To do this, we need pairs of brackets that are never or rarely used ...
