and the verification can be carried out with the formulas given above for 

 6, and h^, ^b^ — b^ and 62 + 2&1, taking (c— i)=V5 + l in Region I as 

 before, and working with 



(26,-6,)(62 + 26,)=tV ^ 26,-6.^0-1 



(c_l+i)i ^2 + 26, c + 1 



c 



It is not difficult to determine the value of c in a quinquisection for 

 K=2K', and to make the algebraical numerical verifications in Table II.
