The term "rhombicuboctahedron" is most commonly used (e.g., Wenninger 1989, p. 27; Maeder 1997) to refer to the 26-faced Archimedean
solid with faces . Cundy and Rowlett (1989, p. 105) refer to that
solid as the "(small)" rhombicuboctahedron, and that convention is followed
in this work, where it is termed the small
rhombicuboctahedron.
The inclusion of "small" is particularly appropriate given the common use of the term "great rhombicuboctahedron"
(Cundy and Rowlett 1989, p. 106;this work) to refer to the 26-faced Archimedean
solid with faces . Unfortunately, to make matters even more confusing,
the terms "truncated cuboctahedron" (e.g., Meader 1997) and "rhombitruncated
cuboctahedron" (Wenninger 1989, p. 29) are sometimes also used to refer
to the great rhombicuboctahedron.
