This name is a “Notariqon” (an abbreviation). Each letter stands for a word and this name stands for Atah Gebor Le-Olam Adonai (You are strong for-ever my-Lord). The only other name of God to include “Gebor” is the name associated with Geburah so for some people this is relevant, but it does not fit neatly so I tend to ignore this interpretation.
Also this name stands for an expression containing Adonai which is frequently associated with Malkuth.
The gematria number associated with AGLA is 1 + 3 + 30 + 1 (35). This is similar to Gabal which means border, boundary or limit.
