The row record type of Unoriented Mirror Classes. This describes the table's public columns, distinct from the mathematical object represented by a row.

The dataset primary key is name. The generated first column id : RowRef<UnorientedMirrorClassRow> links to the row page using that key. It is not stored as a field in the record. String fields render as plain text.

type UnorientedMirrorClassRow = {
    name: string
    unoriented_members: Set<RowRef<UnorientedKnotRow>>
    oriented_members: Set<RowRef<OrientedKnotRow>>
    symmetry: string
    reversible: bool option
    positive_amphichiral: bool option
    negative_amphichiral: bool option
}

Column	Type	Meaning
name	string	The mirror-class catalogue name and dataset primary key.
unoriented members	Set<RowRef<UnorientedKnotRow>>	References to the retained unoriented members.
oriented members	Set<RowRef<OrientedKnotRow>>	References to the retained oriented members.
symmetry	string	Symmetry classification, or Unknown when unresolved.
reversible	bool option	Reversibility from the recorded evidence; None means unknown.
positive amphichiral	bool option	Positive amphichirality; None means unknown.
negative amphichiral	bool option	Negative amphichirality; None means unknown.

RowRef<T> refers to a row of type T, rather than embedding its record. Sets of row references contain clickable members in numeric knot order. Their ordering is for display only; distinct rows can still represent mathematically equivalent objects when identification is unresolved. T option distinguishes a value from None.
