I have a list {1,2,3,4,5,6}
which I would like to associate to another list {a,b,c}
by the rule {1->a,2->a,3->b,4->b,5->c,6->c}
What is the best way to do this without explicitly writing out the associations?
Table[Rule[{1, 2, 3, 4, 5, 6}[[i]], {a, b, c}[[Ceiling[i/2]]]], {i, 1, 6}]
works but is it the most efficient way?
