Everything about Primorial
Product of the first "n" prime numbers
In mathematics, and more particularly in number theory, primorial, denoted by "", is a function from natural numbers to natural numbers similar to the factorial function, but rather than successively multiplying positive integers, the function only multiplies prime numbers. Wikipedia →

📖 Definitions
Noun Any number belonging to the integer sequence whose nth element is the product of the first n primes.
Noun A unary operation, denoted by the postfix symbol # and defined on the nonnegative integers, which maps 0 to 1, 1 to 1, and each subsequent number to the product of all primes less than or equal to it; the value mapped to by said operation for a given input.
