G Q5 By Jeeves! Our friend the butler was so baffled by his counting endeavors he almost forgot that thearriving guests are all married couples (of opposite gender, this being early 20th century England).And, needless to say, no married couple may be seated next to each other. How many seating plansdoes he now have?[If the butler runs out of time before dinner trying to solve this, he can just exhibit a single arrangementthat works and answer the same question for 2 or 3 couples of guests, in addition to the host couple.]
