eigenring, element,
exteriorPower,
factor,
hyper,
kernel,
leftGcd, leftLcm,
Loewy,
makeIntegral, normalize,
polynomialSolution, rationalSolution,
rightGcd, rightLcm,
sections shift and spread.
They are described in detail in the following manual pages.
Note that an element of
can be used
whenever the type of an argument is given as
,
and that computes the Euclidean quotient of
by on the right.
