Hi Troops,

I'm trying to find a simple example that shows the differences between the free, fixed and independent index property. The best that I could come up with is

```
{a,b,c,d,e,f,g,h#}::Indices(position=free).
\Gamma^{a}_{b c}::TableauSymmetry(shape={2}, indices={1,2});
foo := v_{a} \Gamma^{a}_{b c} - v^{a} \Gamma_{a c b};
canonicalise (foo);
{a,b,c,d,e,f,g,h#}::Indices(position=fixed).
foo := v_{a} \Gamma^{a}_{b c} - v^{a} \Gamma_{a c b};
canonicalise (foo);
{a,b,c,d,e,f,g,h#}::Indices(position=independent).
foo := v_{a} \Gamma^{a}_{b c} - v^{a} \Gamma_{a c b};
canonicalise (foo);
```

But that strikes me as too involved. Can anybody suggest a simpler example?

Thanks,

Leo
