i can run now, after remove *, but something not understand yet

LIB "homolog.lib";
int p = printlevel;
printlevel= 1;
ring r = 0,(abc,ac,bc,c),dp;
module M = [0,1,0],[0,0,1],[1,0,0];
module A = [0,1,1],[1,0,1],[1,1,0];
module H = Hom(M,A);


0,0,0,1,0,0,1,0,0,
0,0,0,0,1,0,0,1,0,
0,0,0,0,0,1,0,0,1,
1,0,0,0,0,0,1,0,0,
0,1,0,0,0,0,0,1,0,
0,0,1,0,0,0,0,0,1,
1,0,0,1,0,0,0,0,0,
0,1,0,0,1,0,0,0,0,
0,0,1,0,0,1,0,0,0

why number of columns and rows are not equal to less than or equal to 4 ?

i expect first column represent abc, second column ac

here first equation will be

c+b*c

is it my input M and A are wrong so that are not 4*4 or 3*3 ?
