(By private eMail you told me you are using GAP 3.3 and the Weyl package.)

This is a known error in GAP 3.3, the old version you are using. The current
version 3.4.4 has this error fixed.
If you upgrade to 3.4.4, please note that the Weyl package has been
incorporated in the Chevie package, Frank Luebeck mentioned already.

I hope this is of help.

Best regards,

Alexander Hulpke
