In the series: 13 1113 111113 ... (odd number of '1's followed by a '3'), what's the first prime after 13? In the series: 101 1001 10001 ... ('1' followed by n '0's followed by 'l'), what's the first prime after 101? "There is such a prime and it is constituted of an odd number of digits, but I should like to meet it", writes Professor Ziff. "Where does he get these incessant questions?" writes Professor Rosenberg. Thanks for your help. --Jay Rosenberg ...{decvax,akgua}!mcnc!ecsvax!unbent ========================================================================= Dept. of Philosophy; University of North Carolina; Chapel Hill, NC 27514 =========================================================================
