A k-nacci sequence in a finite group is a sequence of group elements x0,x1,x2,,xn, for which, given an initial (seed) set x0,x1,x2,,xj1 , each element is defined by xn=x0x1xn1,for jn<k,andxn=xnkxnk+1xn1,for nk. We also require that the initial elements of the sequence, x0,x1,x2,,xj1, generate the group, thus forcing the k-nacci sequence to reflect the structure of the group. The K-nacci sequence of a group generated by x0,x1,x2,,xj1 is denoted by Fk(G;x0,x1,,xj1) and its period is denoted by Pk(G;x0,x1,,xj1) . In this paper, we obtain the period of K-nacci sequences in finite polyhedral groups and the extended triangle groups.
