Puzzle 882. Prime sequence type A(Z)iB This is a puzzle that I have created after reading a work by Inder J. Taneja, "Patterns in Prime Numbers: Fixed Digits Repetitions". For the purpose of this puzzle A(Z)iB means AZZZ...ZB where Z is repeated i times. Example: 38(12)351 means 3812121251. We will be only interested in these A(Z)iB that are prime numbers for i=0 to k for some k target. Inder J. Taneja got several (29) solutions for k=9. Example: 291234(3)i73 is prime for i=0 to 9; that is to say: 29123473, 291234373, 2912343373, ... 29123433333333373 are all 10 prime numbers. Q. Send A(Z)iB solutions that are prime numbers for i=0 to k, for k>9.
