The Ninth* Configuration
The ninth in a list of configurations—
is a (2d-1)d
known as the Cox configuration."
— MathWorld article on "Configuration"
futher details on the Cox 326 configuration's
isomorphic to the six-dimensional hypercube γ6 , see
Coxeter, "Self-Dual Configurations and Regular Graphs,"
Bull. Amer. Math. Soc. Vol. 56, pages 413-455, 1950.
This contains a discussion of Kummer's 166 as it
relates to γ6 , another form of the 4 Galois cube.
See also Solomon's Cube.
Title inspired by the novel of William Peter Blatty.
Note that Cox configurations are Tenth, if the fleeting
MathWorld reference to 113 configurations is counted
as seventh— and then the ninth would be a 15 3 and
some related material would be Inscapes.
