A large variety of new extensible wickstetchers, called
greystretchers, were also found, mostly by Keith Amling with some help from Hartmut Holzwart:
Code: Select all
#N c/4 diagonal flat-front greystretcher
#O Keith Amling and Hartmut Holzwart, 15 February 2023
#C The tubs stretched by this pattern have the minimal possible
#C spacing. Such minimal-spacing tubstretchers were previously
#C known, but this is the first known example with a flat, rather
#C than angled, front end.

#N c/2 orthogonal blocked greystretcher

#C known, this example stabilizes the lines with blocks, rather
#C than a period-6 wick.

#N c/4 orthogonal p8 greystretcher
#O Keith Amling, 9 August 2023
#C Although c/4 orthogonal wickstretchers were previously known,
#C this example uses a different wick to stabilize the sides. The
#C interaction between the side wick and the stretcher has period 8,
#C rather than period 4.

#N c/5 orthogonal greystretcher
#O Keith Amling and Hartmut Holzwart, 9 May 2023
#C Although c/5 orthogonal greystretchers were previously known,
#C the new wick-expanding component by Keith Amling allows a greater
#C variety of widths to be achieved than was previously possible.

#N c/3 orthogonal greystretcher
#O Keith Amling, 11 August 2023
#C These were the first c/3 orthogonal wickstretchers of
#C any type to be found. Incredibly, it uses a period-9
#C snake-stretching reaction that quickly becomes
#C period-3 to allow the stretcher to be completed.
