This is exactly what I need ! Thank you @dardoro !
So here is my permutation block :
Since ⍳N is the same function as NUMBERS FROM 1 TO N, I think you should pick one and use it in both slots. I spent a little time scratching my head about whether there was some subtle difference I wasn't getting!
This way, the distinction between the input array and the composition of the cross product is more obvious.
More general use for variations: "n" elements out of an m-element set.
You shouldn't use a list to make a same list
and no enormous list of unnamed variables
All this is tempting me to post the Simplex lock problem again!
Oh ! Thank you @bh for your vigilance ! Of course, this is illogical !
I changed it in order to make it more homogeneous.
I wrote an article about Matrix computations with Snap*!*. This is here and have to be completed with permutations and signatures.

With "Un théorème d’algèbre linéaire en prime ;-)".
I have a presentation on next wednesday (the 6th) at the IREM de la Réunion (depends on the University) about matrix algebra.
When it will be done, I will share my keynote here.
Excellent!

Excellent. An opportunity for me to practice my technical French. :~)

French is close enough to English that, with no one having ever taught me, I can understand that–literally
