@RohitNamjoshi Yeah definitely. It's not particularly active, but it's a nice more private forum.
Got an email you'd like me to send it to? (You should probably email me it or one of our lovely moderators can delete the message after the fact)
My email is my username + a Gmail account

Hi all, I hope it's clear what I want
I have a corrupt Mathematica file and I would like to recover it
Mathematica crashed during a calculation
Wait what, now the AuthorTools trick does work

All right I'm expecting this to be a really well known problem
So I am generating a large array using the following code:
ilLength = Length@InputList;
ilSubsets = Subsets[Range@ilLength, {2}];

ArrayLMNTs =
SlavnovPre[{InputList[[#[[1]]]],
InputList[[#[[2]]]]}, \[Nu], {InteractionStrength,
SystemSize}] & /@ ilSubsets;

(* this excludes the diagonal *)
Print@ArrayLMNTs
The resulting Array is one dimensional of course, ie a depth 1 list
It is generated from coordinate pairs from the subsets
Of course one can generate a 2d array with the elements at the positions from the coordinate pairs, it obeys a certain logic which is well understood
But I believe I'm overcomplicating things, I think ArrayLMNTs can be a 2d array instead, such that the coordinate pair structure is not lost
How would I go about something like that?
Maybe this is even simpler:
f[#[[1]], #[[2]]] & /@
Subsets[Range[3], {2}]
Gives the idea

Maybe this? SparseArray[
Transpose[{xcoords, ycoords}] -> flist, {3, 3}] // MatrixForm
Though it can probably be optimised

Wolfram Blog: On the Polygon Front Lines: Visualizing the Amplituhedron with the Wolfram Language
posted on November 21, 2019 by Gabriele Dian

It’s rare to hear polygons mentioned in a physics class, even in higher education. This may seem unexpected given the fundamental role they play in mathematics. However, over the last few years, polygons have come to the front line in many areas of theoretical physics, helping us understand the laws of nature with their astonishing [...]
