Searching for a string of numbers in a large digit sequence How would one search for a string of digits in a large digit sequence? For example, I'd like to search for 351814 in Euler's number. I'm not too keen on computer science, I'm a pure math major, so I don't really know how to begin. I also wouldn't know how to run said code.   

Any help would be greatly appreciated.
Use your web browser. You can get the first 2 million or so digits in this link, and then use your browser's searching facilities. I was able to locate 351814 within the first 2 million digits (though not within the first 1 million digits, available in a separate link). By the way, I found both links on Wikipedia.
