The function call DisplayPolynomialRing(R) displays the list of ordered variables, the set of parameters and the characteristic of the polynomial ring R.

This command is part of the RegularChains package, so it can be used in the form DisplayPolynomialRing(..) only after executing the command with(RegularChains). However, it can always be accessed through the long form of the command by using RegularChains[DisplayPolynomialRing](..).

$\mathrm{with}\left(\mathrm{RegularChains}\right)\:$

$R≔\mathrm{PolynomialRing}\left(\left[x\,y\,z\right]\,\left\{a\,b\,c\right\}\,5\right)$

$R≔\mathrm{polynomial\_ring}$

$\mathrm{DisplayPolynomialRing}\left(R\right)$

Variables      : [x, y, z]
Parameters     : {a, b, c}
