Is it possible to get access to the group O(1,12,2)?

Gap gives the order of this group, but trials to get (at least part oft
the) character table
fail if one uses the standard commands of GAP.
The character table of the group SO(+1,12,2) = GO(+1,12,2)
is available in the GAP character table library.
It can be accessed as `CharacterTable( "O12+(2).2" )'.
Note that this character table has no group attached to it,
so you cannot ask it for, e.g., conjugacy class representatives.
Hope this helps,
