You can enter your set information in three ways (you can also combine these
ways):
1. Click the notes. Click a note again to remove its pc.
2. Check off the pcs in the integer boxes. Uncheck a box to remove
its pc.
3. Type the integers in the first text field. When doing so,
> Do not use commas.
> Use t for 10, e for 11.
> Type r to reset the text box while
typing.
> Any invalid characters are simply ignored.
Hit Enter / Return to start the calculations. Note: Netscape 4.x users should click the first submit button instead of hitting enter.
If you enter some of your pcs in the text field and then mouse-click the rest, hit Enter / Return (again, Netscape 4.x users should click submit instead) before you start clicking boxes or piano keys. If you don't, only the pcs you've mouse-clicked will be included in the calculations.
You can also type the Forte name of a set class in the second text field.
The calculator displays normal form, prime form, interval-class (ic) vector, Forte name, Forte name of Z-mate (if any), and transposition and inversion levels for set invariance.
The Complement button displays information about your set's complement. The invert button does likewise.
Pull-down menus allow you to transform a set by Tn and TnI operations, to display its class subsets and supersets of each cardinality, and to construct a matrix.
*This calculator does normal form from the right not to the left.
