The xeimtionic comma (pronounced zeem-tee-onic) was discovered by Lumi Pakkanen and Praveen Venkataramana when prompted to create a temperament that produces a 6L 5s MOS pattern so that the pattern could be named xeimtonic.

It defines the xeimtionic temperament. When paired with the frostma 245/242 it produces the desired 6L 5s MOS pattern.

All of this was inspired by an AI generated picture of xenharmonic music theory featuring something that looks like the word XEIMTIONC.
