# Problem using GAP

Hello,

I'm starting to use the GAP package/software with the follow commands to define a simple finite group:

gap> f := FreeGroup("x");

<free group="" on="" the="" generators="" [="" x="" ]><="" p="">

gap> AssignGeneratorVariables(f);

I Assigned the global variables [ x ]

gap> x^5 * x^-7;

x^-2

gap> g := f/[x^5];

<fp group="" on="" the="" generators="" [x]><="" p="">

gap> AssignGeneratorVariables(g);

I Global Variable x already defined and will be overwritten I Assigned the global variables [ x ]

gap> Size(g);

5

gap> List(g);

**Here is the problem, I should get:**

**[ identity ..., x, x^2, x^3, x^4 ]**

but instead, I got:

**[ identity ..., x, x^-1, x^2, x^-2 ]**

1) What am I doing wrong, please?

**Also, the command:**

gap> MultTable(g);

Error, Variable: 'MultTable' must have a value
not in any function at line 8 of *stdin*

Can someone please help with that? I have a lot of ideas on Group / Abstract Algebra but despite I use/read the GAP manual I can't create a simple multiplication table.

Any hint/help will be appreciate.

**Thank you in advance.**
