I have dropped the idea to realize and use variant/2.
The idea is to use only numbervars/3. Here is a test,
testing the newest release of SWI-Prolog as well:

/* SWI-Prolog 9.3.14 */
?- time(test5).
% 39,918,731 inferences, 9.031 CPU in 9.022 seconds (100% CPU, 4420067 Lips)
true.

/* Dogelog Player 1.2.4 */
?- time(test5).
% Zeit 5696 ms, GC 0 ms, Lips 10186409, Uhr 03.11.2024 00:44
true.

The test code is:

test5 :-
    (between(1,1000,_),
       aggregate_all(count, distinct(gen3(_)), _),
       fail; true).

gen3(X) :-
    length(L, 25),
    between(1,1000,_),
    random(Y),
    Z is floor(Y*1000),
    X = [Z|L].

> Ok, I tried a native implementation of variant/2.
> I did it in Dogelog Player for Java. Thats a
> Prolog system that doesn't have unification for
> 
> cyclic terms. So the situation is a little simpler.
> Comparing on the same machine and with the data
> we have already gathered it is shockingly fast!
