Hi Paul,I have tried the sequence you suggsted but when I create the output. It shows an 'undefined control sequence' error. I wonder if besides the preamble is there something else I should do. Thanks.
Oops, I typed something incorrectly. I got the preamble right (\usepackage{mathrsfs}), but in the inset you type \mathscr, then \{, then insert the character(s) you want.
Sorry. /Paul
