Possibility of Errors in Database of Groups of Order Dividing 256

If an error seems to occur when you are using the twogps database, follow this checklist:

You may have overwritten the identifier gps.
If you obtain an error message such as
```
User error: Identifier 'gen2' has not been declared
```
then you have failed to issue the statement
```
load gen2;
```
Other errors may indicate that you are not using gen2 correctly. Type
```
print gen2;
```
to find the correct way to call the function.
If the error is attributable to a bug in the Magma system, send e-mail to magma@maths.su.oz.au with a transcript of your Magma session.
Having eliminated these possibilities, if you have found evidence of a bug in the database data or procedures please document as fully as possible and mail to the authors. Electronic mail addresses are newman@pell.anu.edu.au and obrien@pell.anu.edu.au
