[GAP Forum] Remote access to atlasrep package files

[Alexander Konovalov]

Hi Marek,

for me it works out of the box:

gap> g:=AtlasGroup("Th");
<matrix group of size 90745943887872000 with 2 generators>
gap> 

Are you sure that all dependencies are satisfied:

Dependencies := rec(
  GAP :=
    ">= 4.4.12",                 # do not really need GAP 4.5 features
  NeededOtherPackages :=
    [ [ "gapdoc", ">= 1.2" ],
#     [ "gpisotyp", ">= 1.0" ],
    ],
  SuggestedOtherPackages :=
    [ [ "browse", ">= 1.4" ],    # want `BrowseData.SortKeyFunctionBibRec'
      [ "ctbllib", ">= 1.1.4" ], # want `LIBTABLE.NameReplacements'
      [ "tomlib", ">= 1.2.1" ],
      [ "io", ">= 3.3" ] ],

My guess would be that you did not compile the IO package, so it can't
fetch the data.

HTH,
Alexander
