[GAP Forum] Using M12 semidirect product Z_2 in GAP

[Aniket Joshi]

Hi,

I wish to find the homology H_3(M_{12} : Z_2, Z), where M_{12} is a Mathieu
group of order 95040, and M_12:Z_2 indicates the semi-direct product with
Z_2. I plan to use the GroupHomology(,)  command from the HAP package for
GAP.

How do I use the semi direct product M_12:Z_2 in GAP? Is there an inbuilt
function, or would I need to compute it separately?

Regards,
Aniket
