[GAP Forum] Lamplighter Groups

[fatemeh moftakhar]

Dear Forum

I need to work with Lamplighter groups but the commend "LamplighterGroup"
is not work on my computer. GAP send the message "*Sorry, file
'/cygdrive/D/gap4r7/pkg/fr-2.2.1/doc/chap9.txt' seems to be corrupted*."

Is there other commend for calling Lamplighter groups?

Best regards
Fatemeh Moftakhar
