| Description: The relation used to define ℙ𝕣𝕠𝕛 (and indirectly ℙ𝕣𝕠𝕛n through df-prjspn 42647) is an equivalence relation. This is a lemma that converts the equivalence relation used in results like prjspertr 42637 and prjspersym 42639 (see prjspnerlem 42649). Several theorems are covered in one thanks to the theorems around df-er 8622. (Contributed by SN, 14-Aug-2023.) |
