| Jon E. Schoenfield: @Randy -- thanks ... but the format of your signature is incorrect. It's recommended (per the OEIS Style Sheet) to sign using the four-tilde string "~~~~"; the system will automatically replace that string with your registered username and the date, all in the proper format. Thanks!

Randy L. Ekl defines these numbers as Area numbers (in this case Prime Area numbers); see), so this present sequence are the primes in A280635. If the first partition of digits is the length, and the second partition of digits is the width, then the third partition of digits would be the area, with length*width=area.
