congruence works in this case for divisors of 72 = (2*49-1)-((49+1)/2)=97-25

25 is index of num 49 ( 25+24 ) 07 ( 4+3 ) 07^2 ( z=25) (z+=35) ndx 60 num 119 = 120-1
49 is ndx of num 97 ( 49+48 )

( z+=35 ) 95 ndx of num 189
( z+=35 ) 130 ndx of num 259
for ever ... continue

u see structure :

___ = 777

.._ = 778

replace line for prime

+ ( 776 )
