Blindfold Rubik - Orientamento Spigoli (bozza)

Premessa: per motivi logistici e temporali :-D non ho la possibilità di pubblicare un intervento, sulle regole di orientamento degli spigoli, come vorrei (con le immagini in particolar modo), purtuttavia cercherò di essere ugualmente chiaro.

Per maggiore chiarezza darò le definizioni in base a come io ho scelto di orientare il cubo (rosso davanti, giallo sopra, white below, orange back, left blue, green, right).

I - LAYERS UP and DOWN

First we talk about layered Up and Down (so if you're using my same orientation of the cube, with red and yellow on the front, you know Up and Down with layers that I am referring to those who have their faces yellow and white respectively).

Rule Ia) Consider the edges that have either white or yellow stickers, in which case the edge will be correct if the white or yellow sticker is facing up or down either (that must be Gillo-side or white side) that the edge is white or yellow does not matter, either side can be white or yellow.
Conversely, if the stickers are white or yellow on the sides (I'm always talking about the top and bottom and not the interim, the rules of that I will talk about later in this posting ).... I said, if the white or yellow stickers are located on the sides (front, back, left or right), so if you are above or below, then they are not well oriented.

Rule Ib) While, as far as the other edges (ie those who have not stickers or yellow or white ), the rule is as follows and è simile alla precedente, cioè se lo spigolo ha un adesivo rosso o arancione , tale adesivo deve trovarsi sopra o sotto indifferentemente (quindi sul lato giallo o bianco). Giusto per chiarezza, sottolineo che se ad esempio avete uno spigolo rosso/bianco, dovete applicare la regola I.a e non I.b, perché è presente il bianco. Al contrario, analogamente alla regola precedente, se lo spigolo (che non ha né un adesivo bianco né un adesivo giallo) ha un adesivo rosso o arancione sui lati (quindi davanti dietro a destra o a sinistra) allora è orientato male.

II - STRATO INTERMEDIO

Adesso parliamo degli spigoli that are on the middle layer (ie the edges that are in position 5-6-7-8).

Rule II.a) If we have an edge that has the adhesive, white or yellow, if the adhesive is properly oriented, white or yellow is found (either) in front or behind (ie on the face red or orange) On the contrary, if the adhesive is located on the left or right sides (sides blue or green) is oriented so bad.

Rule II.b) Regarding edges that do not have stickers or white or yellow the rule is different than before, that you must check whether at least one of adhesives has the same color sticker in the center of the adjacent or opposite to an adjacent one, in which case the edge is oriented well, otherwise badly pointed. It 'just that one sticker has the same color as the adjacent center or the opposite.

Example 1: As usual you have before you a red face and over the yellow, then the center front of you is red. We happen for example the front left corner with red (front) and green (left). So the edge has a red sticker and its adhesive adjacent (center) is red, being the same color that it is enough to say that this edge is oriented correctly (although the green is on the left is adjacent to the blue);

Example 2: you always have the red and yellow on front. We happen right in front of an edge colored orange (front) and blue (right). Even if these ores the edge is correctly oriented, in fact, it is true that both adhesives are not the same color of the respective adjacent centers, but they are opposed qeulli, more precisely, before we have an orange sticker which is adjacent the red center, the center red is opposite orange , this is enough for us to say that the edge is correctly oriented. In this particular case the correspondence with the center there is also opposed to the adhesive blue.

For now I ask you to be satisfied with this, I hope, clear explanation, further integrate with the images and maybe with a sample video.
