Please find my results in the attached Excel file. I am 
pretty much confident about both crystal system and volume 
(see the GOF vs. Volume plot, also supported by the number 
of solutions with doubled lattice parameters and high GOF). 
- no acceptable solution with higher symmetry
- the best triclinic solutions require a significant zero 
point error correction

Software: TOPAS (version 3 beta), SVD-Indexing method (Coelho, 2000)
Total amount of time spent on this problem: ~5 Minutes
Calculation time required: ~70 Sec. (PIII / 1Ghz)

Please use my results as you see fit, anonymity is not required.
