|Title||A presentation of the fundamental biquandle of the n-twist spun trefoil|
The fundamental biquandle is defined for an oriented surface link, which is an invariant of it. A surface link can be presented by a ch-diagram which consists of a singular link diagram and some markers. The n-twist spun trefoil has a periodic ch-diagram presentation. Using this fact, we will give a presentation of the fundamental biquandle of the n-twist spun trefoil.
