XYZ-Wing
The three cells {0}, {1} and {2} form an
XYZ-Wing pattern on the value {3}.
Regardless of the correct value of the cell {0} ({3},
{4} or {5}), either the cell
{0} contains the value {3}, or one of the two
cells {1} or {2} will have the value {3} as
its only remaining possible value.
It follows that one of the three cells {0}, {1} or
{2} must contain the value {3}.
Other occurances of the value {3} can therefore be removed from any
cells sharing a row, column or block with all the three cells.
