What reason did ABC give for the change in actor?q
This is closely connected to the group written E7 ( " q " ) , however there is ambiguity in this notation , which can stand for several things : the finite group consisting of the points over F " q " of the simply connected form of E7 ( for clarity , this can be written E7 , sc ( " q " ) and is known as the “ universal ” Chevalley group of type E7 over F " q " ) , ( rarely ) the finite group consisting of the points over F " q " of the adjoint form of E7 ( for clarity , this can be written E7 , ad ( " q " ) , and is known as the “ adjoint ” Chevalley group of type E7 over F " q " ) , or the finite group which is the image of the natural map from the former to the latter : this is what will be denoted by E7 ( " q " ) in the following , as is most common in texts dealing with finite groups .
