Dear Gap-Forum,

Jan Draisma asked:

At the moment GAP 4 implements polynomial rings in countably many
indeterminates and it is possible to take quotients of such polynomials.

However the quotient field itself is not yet implemented and thus I cannot see
any easy way of defining algebras over it.

Sorry for not being able to provide more help,
