Would "Quickly, At The" be better than "Quickly, On The"?

The groups don't quite work - there are several interchangeable items. Crown could be double, triple or quadruple, to make well known phrases. Digits can be single, double, triple etc. Cream can be single or double. Bypass surgery can be single, double, triple or quadruple. Having several that can be directly swapped without affecting the theme of each group, makes it an exercise in luck rather than knowledge and reasoning.
