The link wasn’t working but I found what I think is being shared.

Neo-Nazis also employ various number symbols:

18, code for Adolf Hitler. The number comes from the position of the letters in the alphabet: A = 1, H = 8.[11]

88, code for “Heil Hitler”, a phrase used in the Nazi salute.[12] Also used as a reference to the “88 Precepts”, a manifesto written by white supremacist David Lane.

14, from the Fourteen Words coined by David Lane: “We must secure the existence of our people and a future for white children.”[13]

14 and 88 are sometimes combined with each other (i.e. 14/88, 8814, 1488).[14] They are also sometimes depicted on dice.[15]
