## Regular EOLRb insertions

Normal swap to bring top LR to bottom

For swapping the upper layer LR edge with the edge below it (to get both LR edges on the bottom), do an M/M' move to keep that LR edge on top, then a U2, then the opposite of the first M/M' move

Top LR with matching corners

Do an M/M' move to keep the top LR edge on top, do a U2 then repeat the first M/M' move.

Top LR with opposite corners

Do an M/M' move to move the top LR edge to the bottom, do a U2 then do the opposite of the first M/M' move.

## EOLRb 4C Non-Cycle Influencing

The following solutions are for specific cases where 4C will be a non-cycle case. Influencing begins when EO is solved, and involves inserting LR edges in a non-typical fashion.

For cases not shown, one should insert LR edges normally as shown above. The solutions below typically insert them the opposite way.

The solutions either:

• skip the dots case, resulting in a 4C skip,
• or end up with a 2 or 3 mover 4C (U2 M2 or M2 U2 M2) instead of some 5 mover (e.g. M' U2 M2 U2 M), after AUF'ing when EOLRb is solved.

Either way, they're more efficient.

The cases are quite easy to recognise by only looking at the U-face colors and pattern; form your own recognition methods.

DFDB in ULUR:

2 D-stickers on M slice and U layer

Dots Skip 1

Dots Skip 2

Note: Less efficient than inserting normally and solving dots with E2, but you may prefer this.

Dots Skip 3

The DFDB edge on top (blue white edge in this case) is adjacent to the center of the opposite color (green).

Dots Skip 4

The DFDB edge on top (green white edge in this case) is adjacent to the center of the opposite color (blue).

Dots Skip 5

Dots Skip 6
