%C A104237 A floretion-generated sequence involving Tribonacci numbers. Formula 
               for the g.f. provided by Alec Mihailovs. See sequence A104187 for 
               the sequence generated without using a cyclic transformation (i->
               j, j->k, k->i), i.e. 1lesforrokseq (refer to FAMP Code).
