Sending Mersenne exponents into space
In the spirit of the film "Contact" [only hopefully better] or Voyager...
It occurred to me that the Mersenne exponents (completely unchanged in our symbolic representation  they could easily deduce the symbols are digits, and that we work in base10) might make good candidates for inscription on future Voyager(s) to communicate our civilization's intelligence and progress to ET(s)?

Why not use a binary representation?
Personally, I think sending only 42 Mersenne exponents can only show that our civilization is very poor. I see how they are smiling and asking "why the humans are intrested in Mersenne primes? It is ugly part of math, there is a general formula, stupid humans." I suggest we should stick with sending only some first prime numbers.

I think bearnol's idea is a good one, although I absolutely agree binary representation is more universal.
Binary expression of exponents also fits with the form 2^p 1 which enumerates to strings of 1 in binary. Therefore such encoding might include binary exponent and binary expansion of the related mersenne number (for the first few). Alternatively we could encode perfect numbers in some way. Rather than simply put this on a spacecraft, we should be transmitting this bitstream in the direction of the nearest star using a high power laser beam.

Sending Meresenne exponents into space
:surprised
I am afraid it is a bit late to be thinking of sending messages of numbers altho' succeeding generations will receive the answers and not us living now. NASA had thought about this decades ago and sent a plaque of a man and woman and the Pythagoras theorem figure. No need of figuring out numbers. They figured out that Geom figures are better even tho they might be subject to lateral inversion. BTW The well known constants were also sent such as c. pi, etc. There has been no reply from anyone(alien) so far. Mally

kubus, why should we look smarter than we are?

Thanks your question I realized the more we show the more we can get from aliens. For example if we send the mersenne exponents they can send us back a general formula.
