David stopped at sex and left us almost breathless. But he knows we can have more, much more, with a lot of air to spare.

9 * 10^201 + 1 is prime, otherwise known as the memorable

Nine Sexsexagintillion and One.

If anyone thinks this sounds like

"Sex, sex again 'till yin and one"

you're imagining things. Get back to work!

Suppose that we parse the string "cab", in base p, as
12*p^2 + 10*p + 11. Then "cab" is a prime in the prime
base p = 41, where it evaluates to the decimal number 20593.

Similarly, we may parse the incantation "abracadabra",
in base p, as 10*p^10 + 11*p^9 + 27*p^8 + 10*p^7 + 12*p^6 + 10*p^5
+ 13*p^4 + 10*p^3 + 11*p^2 + 27*p + 10, which evaluates to the prime
8510432846378191 in the prime base p = 31.

The nonce-word "floccinaucinihilipilification" evaluates to the prime
352402927208050896786973658273234894386040810340804173543364510421
in the prime base 199. For the meaning, see

More ambitiously, one might consider the 1185-letter word
for the Tobacco Mosaic Virus, Dahlemense Strain, at
http://www.fun-with-words.com/word_longest.html

By my reckoning, this is probably prime in
20 different prime bases less than 10^6.
