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

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.
