My personal preference is “omegapsical”, by analogy with “alpabetical” (“according to the sequence of the letters of the alphabet”) as opposed to “alpabetic” (“of or relating to an alphabet”). Is that linguistically or etymologically sound? Does anyone know of a rule for (or even an example of) converting a Greek-derived noun ending with “i” to an adjective?
* At least one of these refers to or is derived from the previously-mentioned torrent. One can whittle it down to 40 results by filtering out “DC”, but as “DC” is an omegapsical sequence and might therefor appear in a relevant discussion, I hesitate to do so.
