A list of algorithms for Pyraminx.

Edges of Last Layer: (ELL)

The last layer edges are the three ones sourrounded by the three tips R, L and U (the F face), that makes the edges RF, DF and LF. There are 6 cases in this group, of these one is solved. The occurance is 1:12 (1 skip in 12 solves) so some of the cases are more than once. All algorithms in this group preserves all but the last three edges.

  • Case 1; ... R' L R L' ... "Niklas", cycles (FD)->LF->(RF)->(FD)
  • Case 2; ... L R' L' R ... Mirror N, cycles (FD)->RF->(LF)->(FD)
  • Case 3; ... R' L R L U L U' ... U-PLL, cycles FD->FL->FR->FD
  • Case 4; ... L R' L' R' U' R' U ... Mirror U, cycles FD->FR->FL->FD
  • Case 5; ... R' L R L' U L' U' L ... Orient two, (FR) (FL). The alg is the same as Niklas (y') mirror N.

Last edge on first tip:

The last edge on the first tip is normally the second last step, done before ELL. The edge is in this case RD. In the description the case is where the RD edge is initially, in position or somwhere in the last layer (F face), R side first face-letter and D side second. There are 8 cases in this group, of these one is solved (notated RD just as the edge) and three are mirrors makeing it 5 uniqe cases. The occurance is 1:8 (1 skip in 8 solves). All algorithms in this group preserves LD and RL edges and all four centres, the last layer edges are ignored.

  • Case 1 RD; ... solved.
  • Case 2 DR; ... L R L' R B' R B ... or inverse (you can also use ELL 5).
  • Case 3 RF; ... U B U B' U ... mirror of FD.
  • CASE 4 FR; ... U' R' U R ... mirror of DF.
  • Case 5 FL; ... R L R' L' ... mirror of LF.
  • Case 6 LF; ... R' U' R U ... mirror of FL.
  • Case 7 DF; ... L R L' R' ... mirror of FR.
  • Case 8 FD; ... L' B' L' B L' ... mirror of RF.
