Sequences on which the necessary privileges are missing

If a column has a defaul clause which refers a sequence that the schema in which the table is created does not have rights, the error message is also an ORA-00942:
create table tq84_ora_942 (
   id   integer default other_schema.sequence_name.nextval,
   txt  varchar2(10)
);
Of course, this is also the case if the sequence is selected like so:
select other_schema.sequence_name.nextval from dual;
