If you can do that, please show me how.
Edit: Oh, never mind. No need to bother you with that, since after some study I see from Seaworthy's pictures that the knots #488 and #1434 really are identical. I thought that what Seaworthy was talking about was the variant of a double sheetbend which Svensson mentions, which really is topologically different. Turns out Ashley mentioned it too, and he gives it number 1435.
So, please pretend that I was talking about the difference between #1434 and #1435 all along, because that's what I (foolishly) THOUGHT I was talking about. Possibly because Sam Svensson thought it worth mentioning in his book. #1435 is #1434 with one tuck less, as Ashley says.
Anyway, to make everything perfectly clear, at least in my mind, ABOK#1434 is a twice-tucked double sheetbend, while ABOK #1435 is a single-tucked double sheetbend, that both Ashley and Svensson say are quicker to make than the twice-tucked one. Svensson also says the single-tucked one easier to untie, doesn't jam and is less bulky. It seems to me that it resists slip better as well.
Sorry about my misunderstanding.

PS The picture you linked to is a slipped version of ABOK #1435, and if it wasn't slipped, it would be a perfect picture of the knot I thought we were talking about all along.
