Pro Diskordiány je číslo 23 svaté, je to číslo bohyně Eris, která přežije chaos (Few hold 23 in more esteem than the followers of Discordianism, a self-declared religion based on the premise that discord and chaos are the building blocks of life. For Discordianists, 23 is the Holy Number and a tribute to the goddess Eris, who surveys a world of chaos. The mantra invoked by Discordianists for the Holy Number is „Invert The Pyramid“. If you invert the sentence one letter at a time – eg „dinvert the pyramid“, „id invert the pyram“ etc – it takes 22 chants, finished by the line „The Pyramid Inverts“ to make 23. The last line is called „the final energy releaser“. Discordianism is described by some followers as „a joke disguised as a religion disguised as a joke“.)
