The Index Adapters Pooling Guide, linked [here](https://support.illumina.com/downloads/index-adapters-pooling-guide-1000000041074.html), contains this table along with recommended index combinations for low-plexity library pooling.

**Note**: The orange boxing in the images above illustrates possible low-plex pooling options. See the Index Adapters Pooling Guide, linked above, for more information.\
