[Maxima] ctensor riemann puzzlement

Could someone help me understand the following please?
Like some previous mailing list posters I am working through Schaum's 'Tensor Calculus' (TC) by David Kay.
Without Maxima to remove some of the algebraic grind I would not have got as far as I have.
When I got to Example 8.4 on page 103 I typed in the following to check the example:-
/* The Christoff symbols matched those in TC */
This is where things seem to go a bit awry...
The riemann tensor components returned by Maxima do not match those in TC and also TC claims that for 3 dimensions there are only 6 independant components whereas Maxima returns 8!
Any clarification would be gratefully received.
