Dear Forum,

Are there any function to save GModule data as a C-Meat Axe read-able file ?

I need to use C-Meat Axe because

1. I want to calculate socle series of GModule.
2. I want to calculate a big GModule.

I just made a following little program. But this program is not good
for a GModule over non-prime field.

Thank you.

Gap2MTX:=function( m, name)

local k, q, w, gen, n, repr_idx, file_name, i, j;

 k:=m.field;
 q:=Size(k);
 w:=m.dimension;
 gen:=m.generators;
 n:=Length(gen);
#
 for repr_idx in [1..n] do
#
  file_name:=Concatenation(name,".",String(repr_idx));
  PrintTo(file_name,"MeatAxeFileInfo:=\"matrix field=",q," rows=",w," cols=",w,"\"\n");
  for i in [1..w] do
    for j in [1..w] do
      AppendTo(file_name,IntFFE(gen[repr_idx][i][j]));
    od;
    AppendTo(file_name,"\n");
  od;

 od;
end;
