3719 is not just an old odd number
But a very odd number
With many unique qualities
It is a proud prime number
And not a common composite number
As it has only two divisors, itself and two
It is the smallest prime having all
The end digits of a multi-digit prime
What’s more it is also a rare “Emirp”
Which is “prime” spelled backwards
Being also prime when in reverse
As 9173 is also prime
Its uniqueness doesn’t end there
Its first two digits 37 is also prime
As are its middle 71 and final two 19
The middle two and final two digits
Of its \'Emirp”; 17 and 73 are also prime
But sadly, not its first two 91
As that is divisible by 13 and therefore composite
Finally, of twenty-four permutations
Of our unique prime, six are also prime
But I will bore you no longer with the list
This so-called poem has 23 lines which is also prime!
