##### Update::2008.11.14

This BARS was updated because it was used as one of the BARS-of-the-Week for week 13 of the fall 2008 semester.

```   observe...
23 and 73 are both prime numbers
23 and 73 are both right-truncatable because their
right-most digits can be truncated and the resulting
numbers (2 and 7) are also prime
23 and 73 are both left-truncatable because their
left-most digits can be truncated and the resulting
numbers (3 and 3) are also prime
73 is a "permutable prime" because reversing the
digits results in another prime number (37)
