Spanish term or phrase: tomados de ... en ...

I'm lost here. Beyond my mathematics understanding. This is for year four kids (ESO 4) in Spain. I don't know what they mean here. Anything that would make this simpler would be appreciated as well. As it is, I have to be very literal since I don't understand it. TIA!! To UK English.

ORIG
Las variaciones ordinarias o sin repetición de m elementos, tomados de p en p, siendo p (simbolo para "igual o menor que") m, son los diferentes grupos de p elementos distintos entre sí que se pueden formar con los m elementos, de forma que, en cada dos grupos.

ROUGH DRAFT
The normal or non-repetitive variations of m elements, from p to p, where p (symbol for "less than or equal to") m, are the different groups of p elements without duplicate elements that can be made from m elements such that every two groups:

Explanation:
I believe they mean "taken p at a time" (for example, 3 at a time), where p is less than or equal to m. If you look at the solution to sample question 1 in the link, you have an example.

MPGS	@ Matt 20:58 Dec 27, 2020 Thank you for your 'lexico.com' definition. "at a time" is not short of other meanings: https://www.wordreference.com/es/translation.asp?tranword=at... I don't think this debate deserves any further efforts. Merry Xmas.

@ MPGS. There isn't a time issue. This has nothing to do with time. "At a time" does not refer to a time, but refers to the number of elements you are selecting. "Taken 3 at a time" means only that each subset you take contains 3 elements, as does the next subset, and the next, until you have exhausted the elements contained in the set (not repeated a subset; perhaps also dependent on other additional criteria).

In combinatronics, a 'variation' is *choosing* (selecting / extracting) a sub-set of size 'p' (p, less than m) from a set of 'm' elements.
Whether you do that "at a time" or choosing an element every other day is irrelevant: you end up with a "kosher" 'variation'. :--)

As I said, p at a time, or whatever the given number "at a time". Here is another example:
The number of combinations of n objects taken r at a time is determined by the following formula:

C(n,r)=n!(n−r)!r!

I think it should be 'p at a time'.

Combinations without repetition of 5 elements taken 1 at a time: a, b, c, d and e.

Combinations without repetition of 5 elements taken 2 at a time: ab, ac, ad, ae...

..., de p en p. I believe that it means you can select p objects at a time from the whole amount of m objects that you have. So, if you have 100 children (m=100) you can select them singly (p=1), in groups of two at a time (p=2), .... up to groups of 99 at a time (p=99) i.e. you can select a group of p children at a time (where p≤m).
(It reminded me of "Todos los animales entraron con Noé en la barca, de dos en dos" !)

I have no idea what that might mean. It's possible. It could be completely wrong as well.

Wouldn't it just be "taken from ... to ..."...¿? (although I'm no maths whizzkid either)

choose [ p]

Explanation:
Your original 'chooses ***p**'. Other examples choose k or n (just an optional name for a variable):

'Choose k':
"Variations are arrangements of selections of objects, where the order of the selected objects matters.
To count k-element variations of n objects, we first need to ***choose a k-element*** combination and then
a permutation of the selected objects". https://webpages.uncc.edu/ghetyei/courses/old/S19.3166/pcv.p...
'Choose n':
"Each such choice is called a variation with repetition of m elements ***choose n***. "

from a set of 'm' elements (in your original) you *choose* (select / extract) sub-sets of size 'p' (obviously, p has to be less than m)

taken from 'p' ... on 'p'

Explanation:
The information contains mathematical symbols:
"The 'm' element variations, without repetition, taken from 'p' on 'p', while 'p' is a symbol which is equal to, or less than something. They are different groups of 'p' elements among itself (or themselves), which can be formed with the 'm' elements from both groups."

Example sentence(s):

"Las variaciones sin repetición de 'm' elementos, tomados de 'p' en 'p', siendo 'p' un símbolo para algo igual o menos que algo. Son los diferentes grupos de 'p', elementos entre si, que se pueden formar con los 'm' elementos formados en cada grupo."
