I came across this weird prime number
in the UK press today (31 Oct).
it's the number of the beast '666' with 13 zero's each side (13 considered unlucky) and a 1 - known to math dudes as Belphegor's Prime. Not only is it a prime number (divisible only by itself and 1) but it's also palindromic (reads the same backwards + forwards).
Belphegor's Prime - Wikipedia, the free encyclopedia
Belphegor's Prime: 1000000000000066600000000000001!
I guess it was mentioned 'cos it's Halloween today, and they were looking for a 'spooky' slant.
Happy Halloween !
