Left-Tru Description
Left-Tru is a tool that computes all left-truncatable primes. Left-Tru is a UBASIC DOS program to compute, sort, and output to a file all left-truncatable primes. There are 4260 of them. A left-truncatable prime is a prime number (without the digit zero) that when you remove any of its left most decimal digit, it still represents a prime number (or no number at all if you remove all of the digits). 5167 is a left-truncatable because 5167, 167, 67, and 7 are all prime. The output includes: I LTP 1 2 2 3 3 5 . . . 4258 95918918997653319693967 4259 96686312646216567629137 4260 357686312646216567629137
