|Equivalence class: is obtained from an equivalence relation (reflexive, symmetric, transitive). E.g. from dividing by 3 with remaining 2 2, 5, 8, 11 ... form an equivalence class. E.g. switch positions, e.g. weekdays form equivalence classes modulo 7._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Space/Newton/Genz: instead of space, Newtonian laws know only one equivalence class of spaces that differ in direction and constant speed.
Potential/Maxwell/Genz: even for its potentials there are only equivalence classes of indistinguishable potentials._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
