And what I want you to notice is that when you compute P of Nfor N congruent to four mod five, the answer is a multiple of fiveSo the first person to notice this was Srinivasa RamanujanIn the beginning of the 20th centuryhe proved that it was the case for all numbers congruent to four mod fiveSo he proved that P of five N plus four is congruent to zero mod sevenand that P of eleven N plus six is congruent to zero mod elevenGood?
