Hello. how do I use libremath to input a b modulo m ? I know I can do a equiv b but I do not know how to add m on top of equiv symbol

I was taught this notation:

```
a equiv b ~ ["mod" m]
```

where the modulo constraint is explicitly written at right of the equivalence statement.

However, if you prefer to have *m* superscript over the equivalence operator, you can:

```
stack { size 8 m # a equiv b ]
```

but this is not very nice because you canâ€™t fine-tune the vertical position of *m*.

Here are both renderings:

PS: when asking on this site, always mention OS name, LO version and save format.

`a equiv csup{m} b`

EDIT: I was just testing.

Now I searched for some Help. I can guess that *sup* is for *superscript*, and *c* is for (see @ajlittozâ€™s comment below).*character*

The result of `binom mâ‰ˇ`

is so so.

Almost correct. *c* is for *center*. You have *lsup* and *rsup* variants for positioning superscript at left or right of object. And I didnâ€™t think you could â€śdecorateâ€ť an operator in this way (always thought that super- and subscript applied to variables). Thanks for the tip.
