Description

This is the simplest 3-page diagram of knot 3_1 (the trefoil knot).

This is the simplest non-trivial knot. Its simplest planar diagram has 3 crossings. A list of other knots with small crossing number can be found in [1] and [2]. 3_1 is an alternating knot. It is chiral and invertible. It is also the torus knot of type (2,3). Here we give the simplest 3-page diagram of the trefoil knot. It has 8 vertices. 3-page diagrams were introduced in [3]. According to the notation given in [3] this diagram is encoded by the word a_1a_0a_0d_2d_1c_0c_0c_2.
