Cayley used the following notation in his original paper
A Memoir on the Theory of Matrices 1
My attempt to reproduce the notation is shown below:
documentclassarticle
usepackageamsmath,amssymb,graphicx
begindocument
scalebox2.5parbox0.3textwidth$$
renewcommandarraystretch0setlengtharraycolsep0pt
(mathrmX, mathrmY, mathrmZ)=lower10pthbox$beginarrayr@c@,mkern10muc @,mkern10muc@,mkern10muc l
( &a &b & c & )\
lvert& a' &b' & c' &rvert\
lvert& a'' & b'' & c'' & rvert\
endarray$mkern-6mu(x,y,z),
$$
enddocument
As you will observe the delimiters need to be improved. Any suggestions?
