We construct a rank-1 map T similar to Chacon's map [C], [JRS], but with 2n+1n-blocks in an (n + 1)-block and a single spacer in the middle. Hence T is rigid and the centralizer of T, C(T), is uncountable. We show T is simple [V], [JR], and hence any factor of T is the algebra of invariant sets of some weakly compact subgroup of C(T). We show C(T) has no such subgroups and hence T is prime. Lastly we show that T is graphic in the sense of [AM].
