It is a hybrid of a cube 4х4х4 and cuboid 4х4х5.

How to scramble this cubic 4x4x5 II.Step 1. Side 4х4 in height in

0,5 element - top.

In the any order we alternate turns of a layer

U and algorithms of rearrangements of the dual angular and dual edges of layers

(Uw). Periodically turning a cubic 4x4x5 in space on an axis

Y. Algorithms of a cuboid 4х4х5 here are applied only (

either return algorithms or mirror algorithms). For example:

a)

F2 (R2 Uw' L2 Uw)*2 F2;

b)

F2 (Dw R2 Dw' r2)*2 F2;

c)

F2 (Dw R2 Dw' l2)*2 F2;

d)

(R2 Uw2)*2 R2 Uw (R2 Uw2)*2 R2 Uw';

e)

[(R2 Uw)*2 (R2 Uw2)*2]*2 and any others;

Step 2. Side 4х4 in height in

1 element - top.

In the any order we alternate turns of a layer

U and algorithms of rearrangements of the dual angular and dual edges of layers

(Uw) (algorithms of a cuboid 4х4х5

either return algorithms or mirror algorithms). Also we use algorithms of

3-cycles of piece rearrangements of edges and angular elements of a side 4х4 in height in 1 element for a cube 4х4х4 (

either return algorithms or mirror algorithms):

Here again is not forgotten periodically to turn a cubic 4x4x5 in space on an axis

Y.

At rearrangement by 3-cycles of edges and angular elements, they also

will be developed on a place;

Step 3. Side 4х4 in height in

1 element - top.

We scramble among themselves central elements of average layers of sides 4х5 on the following algorithms (

either return algorithms or mirror algorithms):

a) only between

opposite layers - on algorithm similar to this:

b) in the

any order between the next layers:

It is possible to rearrange steps 1, 2, 3 by places!Step 4. Any of sides 4х4 - top.

We scramble a cubic 4x4x5 on algorithms of a cuboid 4х4х5 - extreme layers parallel to the top side rotating as dual -

Uw and

Dw and all vertical layers we turn

on 180 degrees;

Step 5. We create visual effect

"of the completely stopped puzzle". For this purpose we turn layers of height in 5 elements on 90 degrees in the party of a side 4х4 in height in 1 element and is alternated with perpendicular turns.

Thus it is possible to make 5-6 turns a maximum.

How to solve this cubic 4x4x5 II.Step 1. We get rid of visual effect

"of the completely stopped puzzle". For this purpose in

of a return sequence we turn layers of last step of scrambling of a cubic 4x4x5. It not so is difficult;

Step 2. Any of sides 4х4 – top.

We rotate extreme layers parallel to the top side as dual -

Uw and

Dw and algorithms of a cuboid 4х4х5 is solved

"CAP" on a side 4х4 in height in

0,5 elements. All elements of a side 4х4 in height in 0,5 elements are correctly focused also them more easy to find by a sight. The centre 2х2 of an opposite side 4х4 thus

will solved automatically.

"CAP" is solved so:

а) to solve 4 central elements;

b) to solve edges;

c) to solve corners - as on a cube 3х3х3 at solve of one side;

Step 3. Side 4х4 in height in

1 element - top.

Completely solve all

central elements of average layers of sides 4х5;

Step 4. Side 4х4 in height in

0,5 element - top.

a) we double on colours

at first angular elements of sides

U and

u:

And then edges elements of sides

U and

u:

b) we rearrange already dual elements, and completely we solve layers

U and

u by the same method, as at solve

"CAPS" only in the correct order;

Step 5. Side 4х4 in height in

1 element - top.

a) after solve of the dual side of height in 0,5 elements is restored

(if necessary) all

central elements of average layers of sides 4х5 - with the help of simple algorithms in 4 turns or in a difficult situation - algorithm given in section

" How to scramble ..."( a Step 3, item а));

b) to solve stayed

of edges elements of average layers of sides 4х5 - with the help of simple algorithms in 4 turns, or algorithm:

(R2 Uw2)*2 R2;

c) by algorithms

of 3-cycles of piece rearrangements of edges and angular elements is solved

"CAP".

The basic algorithm of turn of two corners with which help is possible to solve any situation:

And for an example two algorithms of fast turn 3 or 4 corners, which are possible

to not remember:

Example of turn 2 edges with the help of 3-cycles:

d) we double on colours

AT FIRST angular elements, then of edges elements of sides

U and

u.

Example of difficult rearrangement

cross-wise two pairs edges:

e) We rearrange already dual elements and completely we solved layers

U and

u - algorithms of solving of a cuboid 4x4x5.

ОК. THE CUBIC 4x4x5 II IS SOLVED!!!Very difficult and very interesting puzzle.

I RECOMMEND!
