T(5,2) Quick Notes
From Knot Atlas
Jump to navigationJump to search
An interlaced pentagram, this is known variously as the "Cinquefoil Knot", after certain herbs and shrubs of the rose family which have 5-lobed leaves and 5-petaled flowers (see e.g. [1]), as the "Pentafoil Knot" (visit Bert Jagers' pentafoil page), as the "Double Overhand Knot", as 5_1, or finally as the torus knot T(5,2).
When taken off the post the strangle knot (hitch) of practical knot tying deforms to 5_1
