@ana brásio: Can you give an example where it is printed? –  phimuemue Mar 2 '11 at 11:15
The question states that the answer is \mathcal H. So what is the point? –  Caramdir Apr 5 '11 at 15:39
The OP seems to have found its answer by itself and didn't returned to stackoverflow (where the question was originally asked) every since. I'm closing the question because of that. –  Martin Scharrer Apr 5 '11 at 15:57
@Martin: Could as well be deleted in my opinion. –  Hendrik Vogt Apr 5 '11 at 16:54
@Hendrik: I'd leave it open in case the OP returns. –  Caramdir Apr 5 '11 at 22:07
