This is not that weird. If names were random then it would be a 1 in 26^4 = 456976 chance of a particular president matching another for the first 4, but this is a "Birthday Problem" with 44 presidents, so the probability of any two presidents sharing the first 4 characters is 456976!/(456976^44 (456976 - 44)!), which wolfram alpha is giving me a clearly incorrect answer of 0.99793... but anyway, the point is the number won't be that low... where did I go wrong anyone?
