Where most get confused is because of the exponents P,N,A,B,G and H being thrown in there but you must understand that the truth is those variables make up the sextuple T. Where they are pretty much constant variables except h which is either 1 or 0 to determine the outcome of G. P is the finite field 2^255-2^32-2^9-2^8-2^7-2^6-2^4-1. More @Wikipedia
