error message

Or

(%i1) xreduce("+", makelist(f(concat(a,k)),k,0,65))$
(%i2) facsum(%,'operator(f));
Maxima encountered a Lisp error:
 Error in MACSYMA-TOP-LEVEL [or a callee]: MACSYMA-TOP-LEVEL [or a callee]
 requires less than sixty-seven arguments.

Or just

(%i3) apply('ratsimp, makelist(concat(a,k),k,0,65));
Maxima encountered a Lisp error:
 Error in MACSYMA-TOP-LEVEL [or a callee]: MACSYMA-TOP-LEVEL [or a callee]
requires less than sixty-six arguments.
Automatically continuing.

Other than not using facsum, I can't think of an easy workaround.
