No text, but a visual code

EVA-t is the Sun high up away from the lunar node; and EVA-k is the same but at night, with the Sun 180º under the horizon. EVA-p is the Sun in conjuction with the lunar node; and EVA-f, the same with the opposite node.

Wouldn't there be a sequence, always ordered the same of t p k f, then? Even if the glyphs are permuted somehow, wouldn't there be as many t as k as p as f?
