Re: abutment

I suggest to Michael Barr to send the whole sentence where it is found the word "aboutissement", and ask for a translation of the sentence. He will get a better english version that just a rendering into english of that word. May be the natural 21 century mathematical english version of the french sentence will not even use the word "abutment". Michael Barr wrote:

That seems to be the translation of the word, thanks to several. That still leaves that mysterious E^{pq} ---> G^p(E^{p+q}) to correct, since I do not believe that it is correct as stands.
