From Klein’s 1893 Lectures on Mathematics —

The varieties introduced by Wirtinger may be called Kummer varieties….”
E. Spanier, 1956

From this journal on March 10, 2013 —

From a recent paper on Kummer varieties,
arXiv:1208.1229v3 [math.AG] 12 Jun 2013,
The Universal Kummer Threefold,” by
Qingchun Ren, Steven V Sam, Gus Schrader, and Bernd Sturmfels —

Update of 10 PM ET March 7, 2014 —

The following slides by one of the “Kummer Threefold” authors give
some background related to the above 64-point vector space and
to the Weyl group of type E7(E7):

The Cayley reference is to “Algorithm for the characteristics of the
triple ϑ-functions,” Journal für die Reine und Angewandte
Mathematik  87 (1879): 165-169. <http://eudml.org/doc/148412>.
To read this in the context of Cayley’s other work, see pp. 441-445
of Volume 10 of his Collected Mathematical Papers .
