O. k., I am working on the mapping between abelian GAP groups and `GrpAbFinGen` groups.
@fingolfin No, this was a misunderstanding, I am not waiting for more input by Claus.
See pull request #1603 for a workaround.
The group in question is isomorphic to the double cover of the simple group J_2. As far as I know, Magma uses known classifications of maximal subgroups of such groups....
I have made a few experiments. For 2.J_2 as a permutation group (on 200 points), the conjugacy classes of subgroups can be computed in about 5 seconds. For 2.J_2 as...
@thofma Concerning the fancy name: ``` julia> describe(G) "C2 x PSU(5,2)" ```
Thanks for opening this issue. An important feature (since the AtlasRep package takes this approach) of such a data manager should be that only small pieces of the data are...
I think the situation here is similar to that in #4983, where the question was raised whether `ImmutableMatrix` is allowed to convert between list of lists matrices and matrix objects....
@frankluebeck Thanks for the confirmation. I think the (at least) two problems need independent fixes. Concerning the first problem, my questions are as follows. - Is it allowed at all...
I am not surprised about these problems, I was rather surprised that the problems with the previous code (infinite recursion when calling `Kernel`) were not observed earlier. I am still...
