Constructor Detail

KociembaCube

public KociembaCube()

Method Detail

getTwist

public int getTwist()

Corner orientations (3^7 = 2187). Twist is represented as a trinary (base 3) number

setTwist

public void setTwist(int twist)

getFlip

public int getFlip()

Edge orientations (2^11 = 2048). Flip is represented as a binary number

setFlip

public void setFlip(int flip)

getChoice

public int getChoice()

Four middle slice edge positions (12 choose 4 = 495). Choice of the four middle slice edge positions Note that "choice" is for the permutation of those edge cubicles occupied by middle slice edge cubies, as opposed to a choice of all edge cubies within edge cubicles.

setChoice

public void setChoice(int choice)

getCornerPermutation

public int getCornerPermutation()

Permutation of the 8 corners (8! = 40320).

setCornerPermutation

public void setCornerPermutation(int ordinal)

getNonMiddleSliceEdgePermutation

public int getNonMiddleSliceEdgePermutation()

Permutation of the 8 non-middle slice edges (8! = 40320).

setNonMiddleSliceEdgePermutation

public void setNonMiddleSliceEdgePermutation(int ordinal)

Note: None of the non middle slice edge cubies are allowed to be in the middle slice prior to calling this function. If that is not the case, then you must first call backToHome().

getMiddleSliceEdgePermutation

public int getMiddleSliceEdgePermutation()

Permutation of the 4 middle slice edges (4! = 2.

setMiddleSliceEdgePermutation

public void setMiddleSliceEdgePermutation(int ordinal)

Note: All of the middle slice edge cubies must be in the middle slice prior to calling prior to calling If that is not the case, then you must first call backToHome().
