The Proth-Gilbreath Conjecture -display of the process for the 1024 prime numbers following 121288...- [La conjecture de Proth-Gilbreath -visualisation du processus pour les 1024 nombres premiers suivant 121288...-].




This picture displays the process for the 1024 prime numbers following 1212880743808370 (that is close to the G(Pi(1.2125*1015))=811 record) -top row of the picture- with the following colors regarding the numbers:


when all other numbers -{3,4,5,6,7,8,...}- are Grey (Dark and Light Grey respectively for the negative and positive numbers).

According to the Proth-Gilbreath Conjecture, when the first prime number used (the smallest one) is 2, the left-hand side column must be Orange ('-1' or '+1') except the upper square that is Light Green ('+2', the first prime number).
