It's the Weaire–Phelan structure.
(minimum surface foam / honeycomb)
See: https://en.wikipedia.org/wiki/Weaire%E2%80%93Phelan_structure
The Weaire–Phelan structure is based on the unit cell of the A15 structure.
See: https://en.wikipedia.org/wiki/A15_phases
A structure type: https://de.wikipedia.org/wiki/Strukturtyp
(prototypical componds of the A15 structure are: Cr3Si, Nb3Sn)
Note:
When assembled correctly the pyritohedrons never touch each other.
In fact one can get away without printing them at all.
The truncated hexagonal trapezohedrons hold together perfectly well on their own.
They just form voids then.
