I believe the answer is:

array

(Other definitions for array that I've seen before include "Rig up" , "Matrix; display neatly" , "Imposing arrangement" , "Orderly arrangement" , "Significant arrangement" .)

I've seen this clue in the Newsday.com, the Evening Standard, the King Feature Syndicate, the L.A. Times Daily, the New York Times and The Washington Post.
