A piece of mathematical poetry:
313 =The smallest multidigit palindromic prime of the form n * phi(n) + 1, where phi(n) is the Euler function.
A multidigit palindromic prime, how's that for a mouthful? But there are several other interpretations of the number 313. For instance, it's the sum of the squares of two consecutive numbers. (313 = 12^2 + 13^2). Isn't it just a little weird the way prime numbers keep popping up out of nowhere?
And as a reminder of my aeronautical incident... 'Airspeed, altitude and brains – Two are always needed to complete a flight successfully.' I had Airspeed and altitude but missed the third one.
313 can prove that we're all on this flight together.
