table()
Returns the table as a list of lists, using integers to reference the elements.
OUTPUT: The rows of the table, as a list of rows, each row being a list of integer entries. The integers
correspond to the order of the elements in the headings of the table and the order of the output of the
list() method.
EXAMPLE:
sage: from sage.matrix.operation_table import OperationTable
sage: C=CyclicPermutationGroup(3)
sage: T=OperationTable(C, operator.mul)
sage: T.table()
[[0, 1, 2], [1, 2, 0], [2, 0, 1]]
translation()
Returns a dictionary associating names with elements.
OUTPUT: A dictionary whose keys are strings used as names for entries of the table and values that are
the actual elements of the algebraic structure.
EXAMPLES:
sage: from sage.matrix.operation_table import OperationTable
sage: G=AlternatingGroup(3)
sage: T=OperationTable(G, operator.mul, names=[’p’,’q’,’r’])
sage: sorted(T.translation().items())
[(’p’, ()), (’q’, (1,2,3)), (’r’, (1,3,2))]
