The designation CLP means "crossed layers of parallels." The geometry resembles two perpendicular systems of parallel layers joined by alternating tunnels (Brakke, Weber). The figure shows a numerically sampled finite patch of a representative in Weber's construction.
The conjugate minimal surfaces are also triply periodic. They are sometimes included under the same CLP name, although a
general member need not be congruent to its conjugate
(Weber).
