Dear Gap-Forum,

First query: Can one make a trivial PcGroup, and if so, are all PcGroup

operations applicable to it? My problem is that an algorithm of mine

may produce as an answer a PcGroup which happens to be trivial.

Second query: Is there any way of asserting that the type of an object

(say a vector over a given finite field F) will *never* change, in

order that checks do not have to be made if, say, an element of F is

appended to that vector?

Many thanks, Leonard.
