ABoK #2519 : Is it Unique (in book)?

Hi, to the decorative side of knotting!

I’m not sure about this, so ask
Is ABoK #2519 a unique lanyard knot
–or is it somewhere in the " " chapter(s)
under another number (the 770s, 780s, …) ?!

Thanks,

#2519 looks to be a double Wall knot.
Fairly common as is the (single( wall knot used in lanyards.
It is also found in the chapter on Two Strand Lanyard Knots, ABoK #779.

Unless I’m horribly mistaken, that’s the double connection knot (2 strand matthew walker). Tied it twice to be sure I wasn’t imagining things.

In my instructions here, I tie it the same way (but upside down)
http://chineseknotting.org/connection/howto2x2/

Looking at my own records, it’s also #2421

Well, dang, I posted here out of my laziness at actually
tying the darn things … . But respondents are supposed
to do better! ;D

Neither reply is right. (KnotMe is onto #1408, for us
practically minded folk; = 776.) So far, then, #2519
stands as unique, a +1 in the How Many Knots? quest,
which I’m about to wrap up. (spoiler :: 50% of the
about 3,858 #'d images (3x “1/2” plus 1x “a” added to
the “3,854” --and there might be another “1/2” to find.)

Also, initial/leftmost #779 arrow has a bad X-ing,
as judged by rightside & finished knot, and a desire
for symmetry.

Just took another look at this. It seems to me that ABoK #2519 looks more like ABoK #780 where the second “doubling” takes place under rather than over the first tracing. #780 turns out to have a slightly different form (compared to #779) and I like it. But on closer look, the “doubling” in #2519 only goes half-way the second time where #780 goes all the way around again. I like #2519 even more now that I have looked closely.
