sequence(element) fails on list from CAS
sequence or function fails Element 2,3 of ROOTS
It seems to me that Element has a problem to retrieve special complex numbers?
c(x):=x^(3) + (((-3) + (2 * ί)) * x^(2)) + (((-2) - (6 * ί)) * x) - 9 - (3 * ί) makes correct m1 list
Sequence-Command in CAS works correct!
