These are questions asked by jud

As we know, choosing different generators can all represent the same group. But how can I get the combination of these different generators by maple? For example, how do I get the following different combinations of generators of C6?

If I want to get an irreducible polynomial with root sqrt(5) and minimum degree, I can use:

MinimalPolynomial(sqrt(5), x)

But what if I want this irreducible polynomial of the minimum degree to have roots in both sqrt(2), sqrt(3), and sqrt(5)? How do I get this polynomial?

ps: The coefficients are all integers

After this code:

g1 := PermutationGroup({[[1, 2]], [[1, 2, 3], [4, 5]]})

g1:=<(1, 2), (1, 2, 3)(4, 5)>

I can get a string "<(1, 2), (1, 2, 3)(4, 5)>". Could I use the string to restore the PermutationGroup with an elegant method?

lis := SearchSmallGroups('order' = 10 .. 100, 'soluble'): 
seq(DrawSubgroupLattice(SmallGroup(g), 'highlight' = CompositionSeries(SmallGroup(g))), g in lis[10 .. 20])

I want to see if these red nodes are present in each layer and connected at each level, so I need to detect a large number of images. But if I put them in the same row, these images will be very small and I have to zoom in one by one with the mouse to see them. How can I set the size of these images?

ps:I'm currently using my eyes to determine if these red nodes are present at each layer and connected at each level, and I'd be happy if there was code to do this


st := time();
RightCosets(SymmetricGroup(10), SymmetricGroup(11));
time() - st;


Note GroupOrder(SymmetricGroup(11)) is 39916800. It is a very large group. This seems unimaginable to me. Can I know how maple does it?
