use the
conway command, in your example, you'd use
conway 141you might want to fiddle with the
tg1offset parameter to get different effects.
for example, try
tg1offset = 3
conway 141
go 15
the
go command is just to smooth the embedding to get a nicer knot
note that the
conway command will print the equivalent
tangle command string.
in this case
conway 141 is equivalent to the command
tangle 14*1* be sure to read about the tangle calculator by clicking on the help button when on the tangle calculator control panel.
note that although the manual at
http://knotplot.com/manual/commands.html#conway says that only rational knots are possible with the
conway command, this is no longer the case. you can enter, for example, and of the following:
conway 3,4,3,5
conway 8*
conway 21,21,2
conway .2.20
the complete Conway notation is supported. to easily see what's possible, run the
tangles demo in the Knot theory section of the DemoA control panel in KnotPlot.
