    Hello, calculate the rests r1,r2,....of ((....((2^p-2)/p)-r1)/p-r2)/p with 2^p-1 mersenne pirme  I have found that (2^2-2)/2=2 ; 2= 4 div 2 ; for 2^2-1=3

      Hello,
      calculate the rests r1,r2,....of

      ((....((2^p-2)/p)-r1)/p-r2)/p with 2^p-1 mersenne pirme 

      I have found that

      (2^2-2)/2=2 ; 2= 4 div 2 ; for 2^2-1=3

      (2^3-2)/3=2 for 2^3-1=7

      (2^7-1)=127
      (127-1)/7=18 , (18-4)/7=2

      2^127-1: gives the rests R=1,36,52,110,36,39,52,60,8,16,22,81,42,33,34,30,65,38 , 2 ( 2 = 254  div 127 )

      by accident ?

      Maybe  (((2^170141183460469231731687303715884105727-2 )/  170141183460469231731687303715884105727 - r1)/ 170...)..../
       170141183460469231731687303715884105727 = 2


      I know, it is a huge number.
