I have a question about versions of the zeppelin loop.
So far I have seen descriptions of two versions, for example on en.wikipedia.org/wiki/Zeppelin_loop:
- the Rosedahl loop, which is very asymmetrical, and
- an (unnamed) version "where the end seems to be the continuation of the main part, and both ends of the loop seems to be vertical to the main part".
This latter version is symmetrical: the "figure eight" of the zeppelin knot is aligned with the standing end and the working end, and is the legs of th eye are perpendicular to it.
It seems to me that there is a third version, in which the "figure eight" of the zeppelin knot is aligned with legs of the eye, and the standing and working ends are perpendicular to it. (SEE PICTURES 1 and 2).
This version seems to have two advantages:
- it does not extend as far into the loop
- the working end can be tucked under one of the "crossing turns", thereby keeping it out of the loop (SEE PICTURES 3 and 4).
My questions are:
- is this a known knot? is it documented or named somewhere?
- what is known or can be inferred about the properties of this knot?
Thanks in advance,
