Abstract: We consider quotients of the group algebra of the $3$-string braid group $B_3$ by $p$-th order generic polynomial relations on the elementary braids. If $p=2,3,4,5$, these quotient algebras are finite dimensional. We give semisimplicity criteria for these algebras and present explicit formulas for all their irreducible representations.

Key words and phrases: braid group, irreducible representations, semisimplicity.
