Use a LED or a laser or any light source to transmit a prime numbers sequence in binary code. Send the first 10 prime numbers, then repeat the sequence all over again. Do this acoustically also, with tones selected from different frequency interval (20 Hz, 200 Hz, 2 KHz and 20 KHz).

At least this will show that the alien is facing an intelligent being.

I assumed that the alien is intelligent enough so that it can know and understand mathematics and it has sensors for light and/or sound.

How appropriate would it be to communicate this message in an actual transmission to an extraterrestrial civilization?
