While finding research on Sekhmet I camp on a few PDFs and some nice websites. One of the websites claiming to have tried to list all the Sekhmet's found in Lagg made their own list. Which I will type out below for anyone is interested in researching. I am looking into Sekhmet-tefnut.
I am not sure how accurate this list is but I found it quite interesting. I am finding the sekhmet's-Tefnut showing up in a few places. Yay personal research!
