twenty

Twenty: a nice round number. But what other kinds of numbers are there apart from »round«. Three isn't really that triangular, though there's a certain rectilinear aspect to a good, solid four.
Some numbers are long. Others are short. Some you can count at the speed of thought. Some will keep running until they are caught.
And then there are prime numbers. These are really special, hearty numbers. Like prime steak. A sign of the primes.
