 - E2c+) [CLARIFICATION] Although the judge may provide a standard sheet for competitors to submit solutions, a competitor may submit a solution on a different piece of paper, as long as a single move sequence is unambiguously indicated as the submitted solution. (Note that the piece of paper must come from the judge, according to [Regulation E3a](regulations:regulation:E3a).)
 - E2c++) [CLARIFICATION] The competitor's solution must only use moves that are exactly defined in [Regulation 12a](regulations:regulation:12a). Examples of notation and moves that are not permitted in competition: [F], [R, U], [R: U], R'2, L'w, f, M, U2'.
+- E2e+) [CLARIFICATION] Competitors must not derive solutions from any part of the scramble sequence, and solutions should not share significant parts with the inverse scramble sequence.
+- E2e++) [EXAMPLE] Example of solutions that should result in a disqualification of the attempt (DNF): solutions beginning with the same 4 or more moves as the inverse scramble sequence.
 - E3b+) [REMINDER] "Rubik's Cube" refers only to the standard 3x3x3 puzzle.
 - E3d+) [CLARIFICATION] Any stopwatch or watch used by a competitor must not appear to have any functions that would help the competitor find a solution.
 - E3d++) [CLARIFICATION] Competitors should not consider a personal stopwatch or watch as the official time, and must submit their solution after the judge calls "STOP".

     - E2d) The length of the solution is calculated in Outer Block Turn Metric (see [Regulation 12a](regulations:regulation:12a)).
