G21359 is a so-called "gensym" (generated symbol).
What Maxima function generated that return value?
(And for what arguments?)
Gensyms should not appear in results returned to the user.

Well-formed Maxima expressions are like: ((foo) a b c)
that is, the first element is itself a list.
(G21359 1 1) is not well-formed; its first element is an atom.
Most Maxima functions will barf on such expressions.
