There are multiple ways to solve the last seven edges, some of which are listed here.
- Solve one edge in the R layer
- Finish the solve with any LSE variant
While this approach is very easy for people coming from Roux, other variants are more efficient.
- Solve EO and the FR edge
- Finish the solve using L6EP to permute the remaining six edges (e.g. with Roux's 4b and 4c)
- Solve two opposite edges (UL+UR, UF+UB or perhaps even DF+DB) and EO simultaneously
- Permute the remaining five edges using L5EP

- Do 0-5 setup moves and then execute an algorithm to solve UL, UR, FR and EO
- Permute the four midges (edges in M) with Roux's 4c
- Orient two edges and position them at UL and UR whilst bringing either the FR edge or DR edge to the D-layer. Centers must be solved or off by an M2 in 
- Using one OL5E algorithm, the remaining edges are oriented 
- Solve the remaining six edges with special L6EP algorithms 
For one-handed solving, Joseph Briggs proposed that l and l' moves can be used during table abuse to "switch between styles" in order to access all two edges on the R layer. A better explanation is given in his video.
