Tetradic Primes | Function to check if the number N having all digits lies in the set ( 0 , 1 , 8 ).
Function to check if the number N is palindrome.
Function to check if a number N is Tetradic.
Function to generate all primes and checking whether number is Tetradic or not.
Create a boolean array " prime [ 0 . . n ] " and initialize all entries it as true . A value in prime [ i ] will finally be false if i is Not a prime , else true ..
If prime [ p ] is not changed , then it is a prime.
Update all multiples of p.
Print all Tetradic prime numbers.
checking whether the given number is prime Tetradic or not.

How can the above be solved in Python?
