In The Symmetries of Things, John Horton Conway, Heidi Burgiel, and Chaim Goodman-Strauss named this structure hexastix.
[1] The hexastix arrangement has found use in mathematics, crystallography, reticular chemistry, puzzle design, and art.
Michael O'Keeffe and associates define this structure as one of the 6 possible invariant cubic rod packing arrangements.
Rod packings are used to classify chains of atoms in crystal structures, and in the develop of materials like metal–organic frameworks.
If the ends of the prisms in a hexastix arrangement are pointed, the directionality modifies the symmetry and the related structure is known as hexastakes[1].
