I will discuss various ideas used to try to tackle one of the unsolved problems in Richard Guy's book UPINT. Two themes will be parametrised families of curves on the one hand and algebraic surfaces on the other.

[This is a continuation of last week's talk.] A Coxeter group is called a -group if its Coxeter diagram consists of a central node connected to three branches of lengths , , and . I will describe, in the special case , a diagram calculus for the generalized Temperley--Lieb algebra corresponding to this Coxeter group, and discuss how this relates to Kazhdan--Lusztig cells.
