Basic Rules

1. Only different solutions can be submitted.
2. Each solution should let the cube be more closer to solved.
3. In some phases like EO, DR and HTR, the last move must be clockwise. No meaningless half-turns are allowed.
4. Inverse moves are allowed and must be marked with "()" or "^()". "NISS" is not allowed for not mixing with "()".
