Re: [sage-support] run SU as_permutation_group has error
i run in sage is as_matrix_group equivalent to permutation matrix in gap system? i find SU has variable a , which matrix is permutation matrix? i input this result into singular system , it run a very long time for invariant ring. LIB "finvar.lib"; ring R=0,(x,y,z),dp; matrix A[3][3]=2*x,2,1,2,2,0,1,0,0; matrix B(1..3); B(1..3)=invariant_ring(A); S3 = SU(3,3); S3.as_matrix_group() S3.as_permutation_group() [a 0 0] [2*a 2 1] [0 a + 1 0] [ 2 2 0] [0 0 2*a], [ 1 0 0] S2 = SU(2,3); S2.as_matrix_group() S2.as_permutation_group() [ 1 2*a + 2] [ 0 2*a + 2] [ 0 1], [2*a + 2 0] U1 = U(1,3); U1.as_matrix_group() U1.as_permutation_group() On Thursday, June 23, 2016 at 1:13:23 AM UTC+8, vdelecroix wrote: > > And the error message is crystal clear > > AttributeError: 'UnitaryMatrixGroup_gap_with_category' object > has no attribute 'as_permutation_group' > > What do you want to do? > > On 22/06/16 10:29, meInvent bbird wrote: > > S3 = SU(3,3); > > S3.as_matrix_group() > > S3.as_permutation_group() > -- You received this message because you are subscribed to the Google Groups "sage-support" group.

Re: [sage-support] run SU as_permutation_group has error
in gap system in sage cloud, for SU is different from transitive group
how to run for SU to see permutation matrix ?
LoadPackage("sonata");
n:=3;;
name := Filename( DirectoryCurrent(), "test" );;
output := OutputTextFile( name, true );;
for G in SpecialUnitaryGroup( 3, 3 ) do
Display(G);
Display(PermutationMat(G,n,Rationals));
od;
LoadPackage("sonata");
n:=3;;
name := Filename( DirectoryCurrent(), "test" );;
output := OutputTextFile( name, true );;
for G in AllTransitiveGroups(NrMovedPoints,n) do
Display(AsPermGroup(G));
Display(PermutationMat(AsPermGroup(G).1,n,Rationals));
od;

Re: [sage-support] run SU as_permutation_group has error
what is the command to find permutation matrix equivalent to gap command PermutationMat(AsPermGroup(G).1,n,Rationals)) On Thursday, June 23, 2016 at 1:13:23 AM UTC+8, vdelecroix wrote: > > And the error message is crystal clear > > AttributeError: 'UnitaryMatrixGroup_gap_with_category' object > has no attribute 'as_permutation_group' > > What do you want to do? > > On 22/06/16 10:29, meInvent bbird wrote: > > S3 = SU(3,3); > > S3.as_matrix_group() > > S3.as_permutation_group() > -- You received this message because you are subscribed to the Google Groups "sage-support" group.

i find this page http://combinat.sagemath.org/doc/reference/groups/sage/groups/matrix_gps/matrix_group.html it has as_permutation_group but here do not have it On Thursday, June 23, 2016 at 1:13:23 AM UTC+8, vdelecroix wrote: > > And the error message is crystal clear > > AttributeError: 'UnitaryMatrixGroup_gap_with_category' object > has no attribute 'as_permutation_group' > > What do you want to do? > > On 22/06/16 10:29, meInvent bbird wrote: > > S3 = SU(3,3); > > S3.as_matrix_group() > > S3.as_permutation_group() > -- You received this message because you are subscribed to the Google Groups "sage-support" group.

[sage-support] Re: {trac,git}.sagemath.org downtime Wednesday 6/22
there is an issue related to "native git" protocol used to communicate with git server on trac.sagemath. Namely, if you try to use the URL git://trac.sagemath.org/sage.git for (say) fetch it does not get through. (probably a GCE firewall blocks the corresponding port). Using the ssh URL, i.e. g...@trac.sagemath.org:sage.git does work.
