At first I thought this lattice was Swartz's D-surface, later I noticed it has the same topology as Schwarz' P-surface, again later I learned the D and P surface have the same topology. The unit looks the same as the rhombic dodecahedron cell for the D surface, but the units connect differently. Still, the straight lines from both the P and D surface can be found in this lattice.
