17 Oct 2018 Perfect Cuboid 3rd Batch has finished
If a perfect cuboid exists, its body diagonal exceeds 253.

During this batch we were investigating the range of body diagonal from 251 (2'251'799'813'685'248) to 253 (9'007'199'254'740'992).
17'408 face cuboids,
34'816 imaginary cuboids,
156'672 twilight cuboids,
a total of 208'896 different cuboids
were found with the help of 597'095 workunits.

Thanks to everyone who helped to achieve this Great Result. Now we put the subproject on hold for public code review.
