[seqfan] Re: Help wanted: A counting problem concerning the generalized Pauli group

[N. J. A. Sloane]

Simone,  Your problem reminds me a lot of the calculations we did in the paper

227. A Group-Theoretic Framework for the Construction of Packings in Grassmannian Spaces [postscript, pdf, arXiv:math.CO/0208002], A. R. Calderbank, R. H. Hardin, E. M. Rains, P. W. Shor and N. J. A. Sloane, J. Algebraic Combinatorics, 9 (1999), pp. 129-140.

(see item 227 on my pub. list)

- see in particular the formulae in Theorem 1.

I'm not saying this will solve your problem, but it sounds like it
might be related.


 Best regards
