The Gilbreath Conjecture -display of the process for the 128 first prime numbers- [La conjecture de Gilbreath -visualisation du processus pour les 128 premiers nombres premiers-].
This picture displays the process for the 128 first prime numbers:
-bottom row of the picture- with the following colors regarding the numbers:
0 = Dark Yellow,
1 = Cyan,
2 = Light Yellow,
when all other numbers -{3,5,7,11,...}- are Dark Red...
According to the the Gilbreath Conjecture the left-hand side column must be Cyan ('1') except the lower square that is Light Yellow ('2', the first prime number).
