From New Scientist #2204, 18th September 1999
A square field has its sides running north-south and east-west. The field is divided into an 8 × 8 array of plots. Some of the plots contain cauliflower. A line of plots running west to east is called a row and line of plots running north to south is called a column.
John selects a row and walks along it from west to east, writing down the content of each plot as he passes it; he writes E to denote an empty plot and C to denote a plot containing cauliflower; he writes down EECECCEC. He repeats this for the other seven rows and writes down ECEECCCE, ECECEECC, ECCECCEE, CEECEECC, CECECECE, CECCECEE and CCECEEEC. The order in which John visits the rows is not necessarily the order in which they occur in the field.
Similarly, Mark selects a column and walks along it from north to south, writing down the content of each plot as he passes it; he writes down EECECCCE. He repeats this for the other seven columns and writes down EECCEECC, ECECECEC, ECCECEEC, CEECCECE, CECECECE, CCEEECEC and CCECECEE. The order in which Mark visits the columns is not necessarily the order in which the occur in the field.
Draw a map of the field, showing which plots contain a cauliflower.
Enigma 1248 was also called “Rows and columns”.
There are now 1200 Enigma puzzles on the site (although there is the odd repeated puzzle, and at least one puzzle published was impossible and a revised version was published as a later Enigma, but the easiest way to count the puzzles is by the number of posts in the “enigma” category).
There is a full archive of Enigma puzzles from Enigma 1 (February 1979) to Enigma 461 (May 1988), and of the more recent puzzles from Enigma 1048 (September 1999) up to the final Enigma puzzle, Enigma 1780 (December 2013). Which means there are around 591 Enigma puzzles to go.
Also on the site there are currently 53 puzzles from the Tantalizer series, and 50 from the Puzzle series, that were published in New Scientist before the Enigma series started.
