## How to convert a group into a PermutationGroup for...

I can get a group like this:

`g := SmallGroup(48, 8)`

But I want to get the `PermutationGroup` form like `PermutationGroup({[[...]], [[...], [...]]})`. Can we change it into this form?

## Is a bug of IsSubgroup?...

As we know, since the order about the element `Perm([[1, 2], [3, 4, 5]])` of S5 is 6. Then  the C6 is a subgroup of S5, but why `IsSubgroup(CyclicGroup(6), SymmetricGroup(5))` return `false`? Is it a bug?

## How to generate a polynomial corresponding to a so...

Of course, we know the A5 of 60 order is an unsolvable group, but as the wiki here, There are also some solvable groups in the same 60 order. Similarly, although `map(IsSolubleNumber, [60, 120, 168, 180])` will give `false`, there are some solvable groups in orders 60, 120, order 168, and order 180. But how to find these corresponding solvable polynomials by maple? I tried to generate them using random polynomials like this:

```with(GroupTheory);
do
do poly := randpoly(x, degree = rand(6 .. 8)()); until irreduc(poly);
G := GaloisGroup(poly, x);
until IsSoluble(G) and is(GroupOrder(G) in {60, 120, 168, 180});
poly;
galois(poly, x);```

But I didn't get any result even after one night..

## Maple 2021 slow...

Anyone experience a delay in typing as the screen fills with text/math etc.?

I'm using Maple 2021 and as the space is filled typing slows. I can finish typing and watch the last 4 keys enter on the screen.

## Problem running xmaple 2021.2 in Ubuntu 20.04...

Since approximately a week ago, probably after some Ubuntu update, the xmaple 2021.2 interface started to crash after some simple commands, without any error message or log. I tried to run with java (open-jdk) 11 and 8, and I had the same problem. I still have an old 2017.3 version, and it works perfectly. The problem only affects the new Maple release.

Is there some bug report? What can I do?

## How to get a group that meeting the criteria?...

I'm a newbie to maple, I want to get a group that meeting the criteria with this code:

```with(GroupTheory);
G := SymmetricGroup(6);

do

H := Subgroup({RandomElement(G),RandomElement(G)}, G);

C := Core(H, G);

until is(GroupOrder(C) <> 1) and is(GroupOrder(C) <> GroupOrder(H));
H;
C;```

But it's seem I cannot construct subgroup. so I adjust it into:

```with(GroupTheory);
G := SymmetricGroup(6);

do

H := Subgroup({[[rand(1 .. 6)]], [[rand(1 .. 6), rand(1 .. 6)], [rand(1 .. 6), rand(1 .. 6)]]}, G);

C := Core(H, G);

until is(GroupOrder(C) <> 1) and is(GroupOrder(C) <> GroupOrder(H));
H;
C;```

However, it is clear that random numbers do not always satisfy the rules of permutation. So how can I use the loop to generate a random subgroup that satisfies the condition?

How to adapt this program C to Maple ? Thank you.

## Sort non-commutative variables with(Physics)...

Hello!

I'd like to sort variables which are non-commutative and obey certain commuting rules in a preferred order. Here is a minimal example

`with(Physics)`

`Setup(mathematicalnotation = true):Setup(noncommutativeprefix = {q, w}, algebrarule = {%Commutator(q, w) = A}) `

If I want to rewrite `q*w` as `A+w*q` since I prefer the order w>q, what should I do? I tried `sort(Simplify(q*w, algebrarules), [w, q]) `but it doesn't work.

## Long form ScientificConstants GetValue not working...

The long form of ScientificConstants[GetValue] is not working in at least Maple 2021 and Maple 2022

ScientificConstants[GetValue](Constant(g))

This is causing issues for MapleFlow, not being able to call on a constant.

**edit some of the long forms work - specifically the GetValue does not.  I modified the title to reflect that.**

## How do I know exactly which group the GaloisGroup ...

```with(GroupTheory);
G := GaloisGroup(x^5 + 20*x + 32, x);```

I just can get a result like:

`GroupTheory:-GaloisGroup(x^5 + 20*x + 32, x)`

But how do I know exactly what group it is? Actually I know the galois group is D5, But can we use maple to get this information?

## How to get the group in result of DerivedSeries?...

`ds := DerivedSeries(PermutationGroup({[[2, 3, 5, 4]], [[1, 2, 3, 4, 5]]}))`

will get a series group like:

How to get the group by the red line point out? Then I can use `GroupOrder` to get the order of it. I note `GroupOrder[ds[2]]` don't work

## What can block the import of data from Excel?...

I have a student who then she uses tools/assistent/import data and then the file then Maple claims the Excel file is empty? She uses Maple 2021.2. File works on other my and other student computers.

## Selecting and copying...

I have two questions:

1) How can I select only parts of an equation in a Maple Workbook? E.g. I have

4*x^2*(1 + x)^2*(x^2 + 6*x + 1)

and I want to select the text between the first "2" and the "6", but Maple always extends the selection to include the complete bracket. This is very annoying :)

2) How can I copy text from a maplesoft page into a workbook. E.g. I'm looking at

and I would like to select and copy some of the shown examples so that I can use them.

## How can I make maple to show me the Euclidean algo...

Suppose I want to calculate gcd(g(x),f(x))=a(x)f(x)+b(x)g(x) for two polynomial, i.e finding the RHS representation of the gcd, then how to implement this in maple?

I know of the command GCD(f(x),g(x)) but how to find the RHS representation?

Thanks!
