I have a list command from some source code:

```
git clone https://github.com/BVLC/caffe.git
cd caffe
git checkout 8c66fa5f3c04e -b unet_patch
git cherry-pick 458928a

```

I know that the first line will clone a recent version of Caffe code. However, the third and fourth lines will modify the source code. I do not know what `8c66fa5f3c04e` and `458928a` are. From these numbers, can I find the Git hash of the Caffe code?
