Detailed Description

Various algebraic structures.

Function Documentation

REGINA_API std::ostream& regina::operator<<	(	std::ostream &	out,
		const NGroupExpressionTerm &	term
	)

Writes the given term to the given output stream.

The term will be written in the format g3^-7, where in this example the term represents generator number 3 raised to the -7th power.

If the term has exponent 0 or 1, the output format will be appropriately simplified.

Parameters

out	the output stream to which to write.
term	the term to write.
