"Humor can be dissected, as a frog can, but the thing dies in the process and the innards are discouraging to any but the purely scientific mind." -- E.B. White and Katharine S. White (often misattributed to Mark Twain)

this is of limited relevance here: describing the quoted post as humor is a stretch

Showing Mp#52 = 2^x-1 is prime, for prime x > 82589933, is left as an exercise to the reader. (Note, requires showing no Mp have been missed below Mp#51*)
For extra credit, find all the Mersenne primes.

See the relevant portion of https://www.mersenneforum.org/showpo...67&postcount=4 and https://en.wikipedia.org/wiki/Mersenne_prime.
And analogously, F33 is not the 33rd Fermat prime, it's 2^2^33 +1.

A very rational response.

There was once a king who was only 12 inches tall. Terrible king, but a great ruler.

not if it is complex, then by that expression, it may stay complex

If it's complex it means you got a bad digestion.
