I just noticed that it's 60-3 without any divisibility tests.
Tao's 27 prime was much more embarassing but understandable as he's no a calculator.
Savants are for things like remembering the first million primes. Someone like Tao or Grothendieck can't remeber them beyond 20, but it doesn't mean they can't actuly reason about them.
What's Tao's 27 prime again?
Was mentioned in a twin thread:
"27 is a Tao prime. Terence Tao suggested 27 was a prime number on The Colbert Report in 2014. He was likely very nervous."
there was some interview where he illustrated the idea of a twin prime pair using 27 and 29
