Orthogonal group from a form

[katestange]

Hi,

I am new to Magma and the handbook has been helpful to this point but no amount of searching online or in the handbook is answering this question, so I hope you will forgive my asking it.

I would like to create an orthogonal group defined by a particular form on a vector space. I would like to hand Magma a Gram matrix and have it return the corresponding orthogonal group. I cannot figure out how to do this. (I can create a generic orthogonal group, corresponding to the identity matrix, using the built-in functions for classical groups.)

Thank you in advance for any advice.

Kate.

PS - It took no less than a half-dozen attempts to get the Captcha to register. I promise, I'm human!
