| Description: The relation used to define ℙ𝕣𝕠𝕛 (and indirectly ℙ𝕣𝕠𝕛n through df-prjspn 43062) is an equivalence relation. This is a lemma that converts the equivalence relation used in results like prjspertr 43052 and prjspersym 43054 (see prjspnerlem 43064). Several theorems are covered in one thanks to the theorems around df-er 8636. (Contributed by SN, 14-Aug-2023.) |
