Where is the PatchGAN implementation in the official PyTorch CycleGAN repo?
There's mention in the paper and in the code comments of a 70x70 PatchGAN, although I can't find anywhere in the code this is explicitly implemented.

Does anyone know how it is implemented?

I've figured it out. After the last conv layer of the PatchGAN (before average pool) the receptive field size is 70. So each neuron on the single channel feature map (which is 30x30) coming out of that conv layer has information from a 70x70 patch of the input. The corresponding patches overlap one another on the input.
