 OFFSET 1,1 COMMENTS A k-order zip prime, where k<=number of digits, is one which, for all of each set k, form smaller primes when it is "zipped" into k parts by alternately distributing the leftmost digit to the parts. Thus 244712331139 is a 7th order zip prime since we have: k=1 244712331139 k=2 241313 ... 472319 k=3 2731 ... 4133 ... 4219 k=4 211 ... 421 ... 433 ... 739 k=5 223 ... 439 ... 43 ... 71 ... 11 k=6 23 ... 43 ... 41 ... 71 ... 13 ... 19 k=7 23 ... 41 ... 41 ... 73 ... 19 ... 2 ... 3 all primes.
