The seven rows of the table, called periods, generally have metals on the left and non-metals on the right. It can still be used as a checksum to verify data integrity, but only against unintentional corruption.

As A3 and A8 are not further specified, operators can freely choose the concrete algorithms used for A3 and A8. Multi-SIM allows switching among up to 12 stored numbers from the zlgorithm main menu. The COMP hash function is considered weak because there is insufficient diffusion of small changes in the input. They have been known to attack baleen whale calves, and even adult whales.
