G is generated by five elements: x1, x2, x3, x4 and y, subject to the relations

x1^3 = x2^3 = x3^3 = x4^3 = 1

y^12 = 1

(yx1^2)^4 = (yx2^2)^4 = (yx3^2)^4 = (yx4^2)^4 = 1

I'm interested because this group has distinct musical connotations.

hi Charlisque

Why do you think these elements make a group?

I think I've proved they don't, but I'll just check a few things:

(i) These are the only members in the group?

(ii) By group, you mean closure, inverses, identity and associativity?

Say (wnlog)

then

and say (wnlog)

then

which contradicts the closure rule.
