We can't really know what your knot IS,
from this tied-snug image (and no words
--wall or fewer-- to explain. E.g., how many
pieces of rope are there? --1 so 2 ends, or
2 w/4 ends?
The structure reminds me of 3-legged conch/welk
pot bridles, where two legs are formed in one piece
of rope, and the 3rd leg --half-length thus-- makes
a trio by being tied up into the 1-2 legs' apex bight.
One can do this by simply forming the 3rd leg
into a bight of sufficient length and then *hitching*
to this and the folded 1-2 legs' bight (united w/3rd's)
with a sheet bend /becket hitch or --more like your
knot in length, shaping-- the longer Albright knot.
