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.
