EXAMPLE

Find G_6(7):

G_1(7) = B_2(7)-1= B_2(2^2+2+1)-1 = 3^3+3+1-1 = 30;

G_2(7) = B_3(G_1(7))-1 = B_3(3^3+3)-1 =  4^4+4-1 = 259;

G_3(7) = B_4(G_2(7))-1 = 5^5+3-1 = 3127;

G_4(7) = B_5(G_3(7))-1 = 6^6+2-1 = 46657;

G_5(7) = B_6(G_4(7))-1 = 7^7+1-1 = 823543;

G_6(7) = B_7(G_5(7))-1 = 8^8-1 = 16777215.
