It is an easy puzzle to produce CP1 below.
The dictionary entry for Catalog ({) offers
CP=: {@(,&<)
0 1 CP 2 3 4
+---+---+---+
|0 2|0 3|0 4|
+---+---+---+
|1 2|1 3|1 4|
+---+---+---+
But a better Cartesian product could do this:
'ht' CP1 'ao' CP1 'gtw'
+---+---+---+
|hag|hat|haw|
+---+---+---+
|hog|hot|how|
+---+---+---+
+---+---+---+
|tag|tat|taw|
+---+---+---+
|tog|tot|tow|
+---+---+---+
