Smarandache-Wellin number


Given a base b, concatenate the base b representations of the first n primes into a single integer, placing the first prime as the most significant digit(s) and the nth prime as the least significant digit(s). This is the Smarandache-Wellin numberMathworldPlanetmath Sn.

For example, in base 10, S8 is 235711131719, the concatenation of the strings “2”, “3”, “5”, “7”, “11”, “13”, “17” and “19” reinterpreted as a single integer.

Placing a decimal point immediately preceding a base 10 Smarandache-Wellin number turns it into an approximation of the Copeland-Erdos constant.
