== 1+4000 = 4001? I know this isn't your question. give me the real number

haha... cute. oops, I guess I forgot an essential part of the problem.... that should be "If (1+4k) is _prime_, can it be expressed as the sum of squares? If so, what's the proof of this..." btw, for technicalities sake, let k be a variable!! cute matt ;) thanks again.... Carrie Anne
