I don't have it around, but I don't remember it being there - as far as I recall he just performs the computation you presented above. I agree that your question is natural, and deserves a modular answer. Weird part is - it also deserves the answer I've given - and I've never seen it either. | |

| Nov 18, 2012 at 9:03 | comment | added | IMeasy | yes I do agree with you, this should be so. I wondered if there was any modular explaination to the the 2:1 cover, but maybe it is just that they are the halves, as you point out. thank you for your answer. | |
